Micro pH/blood gas analyserRadiometer has introduced a pro-grammable micro pH/blood gas analyser,the ABL3 Acid-base laboratory. Itmeasures pH, PCO2, PO2, haemoglobinand barometric pressure and calculatesseven additional parameters. Toperform a measurement, the operatorneeds only to introduce the 125capillary sample. All other functions,such as rinsing, calibration andrecording of results, are performedautomatically. A keyboard and screen(CRT) allow for communication withthe built-in computer. The CRTprovides information concerning theperformance of the ABL3, calibrationdata, warning etc. The keyboard allowsfor requesting special programmes suchas setting calibrating drift limits, enteringPso values, or changing the frequencyof the one- and/or two-point calibrations.Special programmes for soaking,adjustment of the haemoglobin or bar-ometer channels and selection ofconventional or SI units are alsoavailable.Radiometer AIS, 72 Emdrupve],DK-2400 Copenhagen NV, Denmark.

TLC spot applicationThe Camag Nanomat available fromBaird & Tatlock enables spot applicationof quantitative and qualitative samplesin TLC, especially in HPTLC. Theapparatus is suitable for linear TLCplates and for circular chromatograms.The transfer of the sample is made bycapillary pipette, eg, glass capillary fornormal TLC layers, application capillarywith Pt-lr tip or fixed volume dosagepipette for HPTLC plates. The capillarypipette is filled externally from theapparatus and placed in the openingof the magnetic head where it is heldabove the layer. A release button ispressed and lowers the capillary on tothe TLC plate and discharges itscontents. It then returns automaticallyto its original position and is removed.Speed of lowering and delay time on thelayer are controllable. With correctadjustment damage to the layer is pre-vented. Positioning notches at 5mmintervals for linear application and at15 on the turntable for circular appli,cation facilitate the operation. Theprecision of the application is claimedto be very high.

it can operate in two modes: as a 400line FFT analyser sampling the inputand transforming lk samples at a timeinto the frequency domain and so pre-senting a constant bandwidth spectrumat 400 equally spaced frequency inter-vals across a frequency range of 0 to20 kHz; and as a high resolution analyseroperating on 10k samples of the input,ie a ten times longer time function. Inthis way any selected tenth part of thefrequency spectrum chosen can be’zoomed’ to fill the entire displayscreen with the 400 line frequencyintervals, thus making possible a 4000line frequency analysis of the totalspectrum. The most important pointabout this is the repeatable ’zooming,without recording a new time function.The 2033 can also apply ’scan’ analysis.In this mode it is possible to extend thetime of a transient signal so that it canbe analysed in slow motion. The 2033has several other features which makesit suitable for use in the analysis ofacoustic and vibration signals, shocksand transients, machine run-ups, vibra-tion of cyclic machinery, order analysisetc. and-it can be connected to IEC625/IEEE Std. 488 interface bus.B & K Laboratories L td, Cross LancesRoad, Hounslow, Middlesex, UK.

Digital cassette recorderB & K Laboratories announce the releaseof a new digital cassette recorder. Thisrecorder Type 7400 as it is known offersa solution to the problem of recordingdigital outputs from measuring instru-ments. Up to 500k-Bytes of data, trans-mitted over the IEC/IEEE or B & K lowpower interface bus, can be recorded ona standard digital tape cassette and re,

constructed on the bus later. The 7400incorporates manual and remote control,and the recording formats used meetECMA 34 and ECMA 41 (basic system).As the recorder can be manually as wellas remotely controlled, it can be usedindependently of an IEC/IEEE controllerin recording or reading data in the field.A 4-digit tape location display indicatesthe position of the tape and a searchfunction can be used to speed theretrieval of recorded data. Here thelocation of the data is entered into the

7400, which then makes a search throughthe tape for the location. The datastanding at that location may then beread over the interface bus, or new datarecorded. Remote control of the 7400is over its interface which is compatiblewith IEC 625-1 and IEEE Std. 488.Cassettes recorded on the 7400 can beread by ECMA compatible computerterminals, and vice versa. The recordercan record or read data at 1000bytes/second (average) with a tape speedof 15 ips. Error checking proceduresare incorporated. The search speed is30 ips and the rewind speed is approx-imately 100 ips. The 7400 recorder canbe powered from an AC or DC source.B & K Laboratories L td, Cross LancesRoad, Hounslow, Middlesex, UK.

Data acquisition systemPye Unicam have introduced the PhilipsPM 4001, a universal data acquisitionsystem for scientific and industrial appli-cations. This system is based on the PM4000 compact data logger withadditional hardware and software. The.system can handle up to 950 analogueand/or digital inputs using IEC-625instrument bus and parallel interfacesas well as a combined V24 (RS232C)/20mA interface card. Thermocouple andPt100 resistance thermometer linearisa-tion is standard and strain gaugemeasurements can be performed. ThePM 4001 is a completely modularsystem. The mainframe holds 50 inputchannels while satellite input units hold100 channels each. Data processingfacilities allow conversion from imputvoltages or currents to various physicalvalues following the formula M ax +b, where a and b are constants. Physicalunits can be added on outputs. Calcula-tions of mean values and sums of thedifferent analogue and digital inputs arealso possible. An ouput buffer allowsstorage of values that cannot be .feddirectly to a peripheral unit.Pye Unicam Ltd, York Street, CambridgeCB1 2PX, UK.

In-sync multi-channel tracesAll standard multi-channel hardcopyrecorders with three or more channelsnormally provided out-of-sync traces,making it difficult to analyse results ofmass chemical analyses, especially whenthe required signal has a small amplitudeand high noise level, and when all tracesare fully overlapping. With the BryansSeries BS314 or BS316 mainframefactory-fitted with the DataSyn Unit allthe traces are in time-synchronisation.An optional feature available with thisunit is an IEEE-488 1978 interface,which allows the recorder to be operatedvia the standard IEEE and IEC interfacebus commands. These interfaces arecompatible with talk and listen modes.Bryan Southern Instruments Ltd, WillowLane, Mitcham, Surrey, CR4 4UL, UK.
