1. General This PT was provided in the context of the AQS Baden-Württemberg drinking water PT scheme. In collaboration with IWW Water Centre (Mülheim an der Ruhr) this inter-laboratory comparison study on metabolites of pesticides and Glyphosate was also carried out under the umbrella of the NORMAN Network of Reference Laboratories for Monitoring of Emerging Environmental Pollutants (http://www.norman-network.net). Following metabolites were provided: metabolite metabolite of Desphenylchloridazon “metabolite B” Methyl-Desphenylchloridazon “metabolite B1”

These recommendations “for the execution of PTs for the measurement of chemical parameter and indicator parameter for the external quality control of drinking water laboratories” (Bundesgesundheitsblatt 46 12, 1094-1095) require, that drinking water laboratories must demonstrate their com-petence for all parameters they are accredited for or they want to be accredited for by a successful participation in a PT round within a cycle of 2-3 years. The PT was executed and evaluated according to the requirements of the DIN 38402-A45 and ISO/TS 20612.

PT 2/10 – TW O5 page 4 2. PT design Each participant received the following samples:

• 3 samples for the determination of the metabolites in 1000-ml-glass bottles with screw cap; sample preservation by cooling.

• 3 samples for the determination of Glyphosate and AMPA in 1000-ml-glass bottles with screw cap; sample preservation by cooling.

3 different concentration levels/batches were produced. All participants received each concentration level. 3. Sample preparation The samples for the determination of the metabolites and Glyphosate were based on a real ground water matrix. The ground water was filtered by using 5 µm and 1 µm filter cartridges to eliminate particles. To reduce germs, the ground water was irradiated with ultraviolet light and was pasteurised at 80 °C in a stainless steel vessel overnight. During pasteurisation the matrix was aerated with a mixture of carbon dioxide and nitrogen to prevent de-gassing of carbon dioxide followed by precipitation of calcium carbonate. For the preparation of the samples, the matrices were spiked with stock solutions and the concentrations covered drinking and ground water relevant ranges. The samples were cooled directly after preparation. The samples were dispatched with freezer packs added to the packages. 4. Sample distribution The samples were dispatched on 8th March 2010 by express service.

PT 2/10 – TW O5 page 5 5. Analytical methods The participants were free to choose a suitable method, but a limit of quantification of 0,05 µg/l for all analytes were required. The samples had to be analysed in duplicate over the complete method (sample preparation and measurement). The participants were asked to submit the results in µg/l with four significant digits. 6. Submission of results The deadline for the submission of results was on 26th March 2010. 7. Evaluation procedure The statistical evaluation was executed according to DIN 38402-A45 and ISO TS 20612 “Interlaboratory comparisons for proficiency testing of analytical chemistry laboratories”. From the participants’ results a relative standard deviation was calcu-lated for each concentration level and parameter using the Q-method. The Hampel estimator was used for the calculation of the consensus mean which was used as assigned value xa. The standard deviation for proficiency assessment σ) was taken from the Q-method for the calculation of the zU-score according to DIN 38402-A45 or ISO TS 20612 respectively in those cases, when the relative standard deviation was within the limits. σ) was limited as follows: lower limit: 5 % upper limit: 25 % The limits were used as σ) , when the relative standard deviation derived from the Q-method, was above the upper limit. A z-score was calculated for each measurement result derived from the assigned value xa and the standard deviation for proficiency assessment:

σ̂axresult

scorez−

=−

The z-score was modified to a zU-score with a correction factor for proficiency as-sessment (as described in the standards mentioned above). The tolerance limit was defined as IzUI=2.0. 8. Assessment There was no overall assessment of the proficiency test round, but the single pa-rameters were assessed. A parameter was assessed as successful, if more than half of the values were cor-rectly determined (2 out of 3 values were within the tolerance limits). Not successful were:

1.) Values which were not determined (if the other samples of this parameter were analysed),

2.) Values, which were indicated with “lower than limit of quantification”, 3.) Values, which were subcontracted, 4.) Values, which were submitted after the deadline of submission of results.

PT 2/10 – TW O5 page 7 Parameter tables

In these tables the following values for each concentration level are listed:

• assigned value • expanded uncertainty of the assigned value in %, calculated according

to ISO 13528 using the formula

values of number

deviation standard rel.25.12U ⋅⋅=

• standard deviation, calculated using robust statistical method • standard deviation for proficiency assessment for the calculation of zU-

scores • rel. standard deviation for proficiency assessment • tolerance limits above and below • permitted deviations above and below in % • number of values in this level • number of not satisfactory values below and above the assigned value

and the percentage of these values in total. Determination of recovery rate

In the diagrams of the assigned values versus the spiked amount of analyte a linear regression line was calculated using a generalized least square regression which takes into account the uncertainties of the values in both directions. From these val-ues the recovery rate for each parameter was determined (see diagrams). The slope of the line indicates the average recovery rate. The diagrams also contain the ex-panded uncertainty (k=2) of the mass values and the assigned values. Relative standard deviations and tolerance limits

The diagrams for the relative standard deviation vs. the assigned value show the concentration dependency of the standard deviation and the tolerance limits in per-cent. The relative standard deviations calculated from participants’ data are the stars con-nected by an interrupted line, the rel. standard deviation taken from the variance function (and sometimes limited by the upper or lower limit) are given by squares, connected by a continuous line. Method specific evaluation

For each parameter the methods used by the participants are shown in a diagram. In a second diagram for each method with a frequency of more than 5 %, values are sorted in 5 categories: too low results with zU-score < -2 low results with –2 ≤ zU-score < –1 correct results with –1 ≤ zU-score ≤ +1 high results with +1 < zU-score ≤ +2 too high results with zU-score > +2

PT 2/10 – TW O5 page 8 Comparison of means and reference values for each concentration level

Finally the mean value calculated from all results (used as assigned value) is com-pared with mean values calculated for all methods separately (in this case using the Hampel estimator described in ISO/TS 20612). Mean values were calculated only, if more than 7 results were within a z-score-range of ± 2. The means are reported with their expanded uncertainty calculated according to ISO 13528. 11. Explanation of Appendix B Participants were asked to report expanded uncertainties of their results on a volun-tary basis. In this diagram for each parameter the reported uncertainties for all con-centration levels with the reproducibility standard deviation (horizontal line) are dis-played. Values which deviate from the reproducibility standard deviation with a factor more than 2 are usually not realistic. 12. Explanation of Appendix C In the last part of the report, for all concentration levels the results of all participants are illustrated. Confidentiality of participants is ensured by using lab codes. The lab codes were sent to participants with the certificates. In detail Appendix C contains:

- a table with all data - figures with

o all reported results o all zU-scores o all reported expanded uncertainties o all ζ−scores

Table with all data

The assigned value with the expanded uncertainty and the tolerance limits for the concentration level is illustrated in the table. For each participant the following data are given:

• lab code • reported result • measurement uncertainty of the value (if reported) • ζ-score for this value, calculated with the following formula

22reflab uu

xx+

−=ζ , with

xx − = difference from the measured value and the assigned value • ulab = standard uncertainty of the value, reported by the participant • uref = standard uncertainty of the assigned value • zU-score for proficiency assessment • assessment of the value according to its z-score

Meaning of ζ-scores: The assessment of ζ-scores is similar to that of z-scores. If the data are normally dis-tributed and the uncertainties are well estimated, ζ-scores will lie between -2 and +2 with a probability of around 95 %. ζ-scores are mainly influenced by the measurement uncertainties reported by the laboratory. Therefore ζ-scores are usually not appropriate for the assessment of the reported results, unless the reported measurement uncertainty is checked for fitness-for-purpose.

Page 11: Analytische Qualitätssicherung Baden ... - Uni Stuttgart · University of Stuttgart Bandtäle 2, 70569 Stuttgart-Büsnau, Germany on behalf of the Ministry of Rural Affairs, Food

PT 2/10 – TW O5 page 9 Therefore we do not use the ζ-scores for the assessment of the laboratories. Nevertheless ζ-scores are appropriate to check the plausibility of the reported meas-urement uncertainty: If the z-score of a result is within the tolerance limit and the ζ-score is outside, then the measurement uncertainty is underestimated. If the z-score is outside the tolerance limits and the absolute value of the ζ-score is lower than two, then the requirements of the proficiency test were stronger compared with the reported measurement uncertainty. Diagrams of uncertainty data In the first figure for all lab codes the measurement uncertainty (together with the re-producibility standard deviation) is illustrated. The second figure shows the associ-ated ζ-scores. 13. Measurement uncertainty 22 (30,99 %) out of 71 laboratories with valid values reported measurement uncer-tainties. In total 357 (20,01 %) out of 1784 valid values were given with the meas-urement uncertainty. The following table displays the number of values with measurement uncertainty against the accreditation status.

Accreditation status of the values

Number of values

Number of values with meas-urement uncertainty

accredited 432 162 (37,5%) not accredited 504 79 (15,67%) not specified 848 116 (13,68%)

We would like to put emphasis on the fact that reporting of measurement uncertain-ties in our PT scheme is absolutely voluntary. The only objective is to help all partici-pants to reasonably handle measurement uncertainties and their estimation. The diagrams show that the spread of reported uncertainties is vast, from unrealistic low values up to very high. A plausibility check using reproducibility standard devia-tions of the PT round could be helpful here. If measurement uncertainties are underestimated values assessed as “satisfactory” in the PT (|z| ≤ 2), will have a large ζ-score. |ζ| > 2 means that the “own” require-ments (defined in terms of estimated uncertainty) are not fulfilled. 18 (5 %) of the 357 values reported with uncertainties and having a z-score |z| ≤ 2.0 had a ζ-score > 2.0. This means that the requirements of the PT scheme have been fulfilled , but not the “own” requirements, the uncertainty is underestimated. 14. Traceable reference values Traceability of analytical results to national and international references is of increas-ing importance in all laboratories. This is not easy to realise for chemical analyses and often can only be done by analysing certified reference materials. But availability of these reference materials in the water sector is very limited. Therefore we try to provide reference values for the proficiency test samples, traceable to national and international references. Since our PT samples without exception are spiked, real water samples, reference values can be calculated from the sum of matrix content and spiked amount of ana-lyte. For both summands traceable values and their uncertainty have to be deter-mined. Thereby we assume that no unrecognised bias resulting from sample prepa-ration and transport is present and that we recognise all uncertainty components.

PT 2/10 – TW O5 page 10 Determination of the spiked amount and its uncertainty

All spiking of samples was controlled gravimetrically. Conversion to concentration was done by measuring the density of the resulting samples using a pycnometer. This procedure allows the preparation of a complete uncertainty budget. The first step is the specification of the measurand with a formula. This shows the links between the result and all influence quantities.

The following figure shows a typical distribution of the contributions, here for metabolite B as an example. The main contribution results from the purity of the standard solution.

All weighings were done as difference weighings. The precision of these weighings was determined in experiments by multiple (20fold) measurements of mass pieces with similar masses as a type A uncertainty. The trueness of the weighing, that has to be considered twice for each weighing, was taken from the calibration certificate of the balance. Maintaining of these tolerances is assured by regular maintenance of the balances by a calibration laboratory and by supervision with our mass pieces (calibrated by an accredited calibration laboratory). The determination of the density was also made using weighings (of the pycnome-ter). The above said also applies here. Temperature measurement was made with a calibrated thermometer. The purity of the used metabolite (99,5 %) was taken from the certificate of the manufacturer. The manufacturer reported an expanded uncertainty of 2 %.

PT 2/10 – TW O5 page 11 With all these uncertainty components the combined uncertainty, as described in the EURACHEM/CITAC-Guide „Quantifying Uncertainty in Analytical Measurement“, was calculated using the sensitivity coefficients determined by partial derivation of the formula to the respective influence quantities. So traceability was assured by using calibrated balances and thermometers. Determination of the matrix content

Because the same matrix was used for preparation of all samples, the matrix content could be calculated from the mean values of the participants and the spiked amounts in a standard-addition-like way1,2. The uncertainties of the spiked amounts were known from the uncertainty budgets. The expanded uncertainties of the mean values of participants’ result were calculated according to ISO 13528 (Statistical Methods for Use in Proficiency Testing by Interla-boratory Comparisons) as

nsu R

mean ⋅⋅= 25,12

with: sR reproducibility standard deviation n number of data for this level 2 coverage factor for the expanded uncertainty 1,25 correction factor (according to ISO 13528 to be used for robust methods) The content of the matrix can be derived from a linear regression of means vs. spiked amounts. Since uncertainties of all data points were available for x- as well as y-direction a generalised least square regression was used as described in DIN EN 6143. The computer program B_LEAST (from BAM) was used for this purpose. With this method a value for matrix and its uncertainty are obtained. Because of statistical variation of the input values the calculated matrix content might result in a negative value. From a scientific point of view this of course is nonsense. In those cases the matrix content is set to zero. The lower end of the uncertainty range of the matrix content also might be negative. Therefore the expanded uncertainty of the matrix content was set to the matrix con-tent itself in this case. The matrix content is not directly traceable to national or international references, but it does not considerably compromise the traceability of the final content due to its comparably low contribution. 15.
