Read this user manual carefully before using the OCT-1 8-Port Sampler to ensure its proper use. The manual should be conveniently stored for future reference.

CAUTION

Safety may be compromised if the 8-Port Sampler is used in a fashion other than that indicated in this user manual. Pay particular attention to the CAUTION sections to ensure safety when using the sampling unit.OCT-1

1.2 Operational Precautions1.2 Operational Precautions Take the following precautions when using the OCT-1 8-Port Sampler.

CAUTION

Hand tighten the various connectors to the 8-port valve. Use of a tool may cause deformation and leakage in the valve.

Stop operation of the instrument when performing maintenance on any of the drive components, such as connecting lines to the 8-port valve, or connecting/ disconnecting lines on the sample injector. If these parts are manipulated or if the lines are disconnected during operation, the drive component could move, causing injury or discharge of liquid.

To clean the OCT-1 8-Port Sampler, wipe the surface with a soft cloth moistened with water. Do not use chemicals.

Repairs to the inside of the TOC-V can be dangerous. Contact your Shimadzu representative to have a trained service engineer perform any repairs.

Do not disassemble or modify the OCT-1 8-Port Sampler beyond the scope of the maintenance procedures in this manual as safety may be compromised.

1.4 Maintenance

1.4.1 Replacing the 8-Port Valve Rotor

1.4 Maintenance


The OCT-1 uses a fluororesin 8-port valve rotor. The valve rotor may become worn or scratched after prolonged use due to the suspended particles in the samples. This wear eventually causes leaks from the 8-port valve.

The following symptoms are associated with leaks from the 8-port valve and indicate that it is necessary to replace the rotor.

Droplets of liquid around the 8-port valve (especially, around the upper shaft) Decreased analysis reproducibility.

Presence of bubbles in the syringe of the TOC-V unit.

If the leakage is great, sample remaining in the tubing after the syringe has been filled may flow back into the sample container. This phenomenon is most likely due to a sample tubing, flange connection problem.

CAUTION

Switch off the power before replacing to the 8-port valve rotor.

Replacement Procedure

1. Shut down the TOC-V unit and switch off the power.Reference: Refer to Ending Analysis in the Operation chapter of the TOC-V User Manual for details on

shutting down the TOC-V unit.

2. Remove the 4 screws at the top of the 8-Port Sampler, and take off the cover.

3. Verify that the O mark on the 8-port valve cover is directed toward port No.1. Note: If the O mark is not directed toward port No.1, the instrument was not

shut down properly. If this is the case, turn the TOC-V on again, and shut it down properly. 5OCT-1

22Operation

This chapter describes the measurement procedures for the 8-Port Sampler as they pertain to TOC-VCS, TOC-VWS, TOC-VCP, and TOC-VWP models. These operations are similar to those of the ASI-V autosampler. Only the operations that differ from the ASI-V are described in this chapter. For more detailed information, refer to the documentation provided with your particular TOC-V model.

2.1 CS OperationThe operations that differ from the ASI-V as the relate to the TOC-VCS model are described here.

2.2 WS OperationThe operations that differ from the ASI-V as the relate to the TOC-VWS model are described here.

2.3 CP OperationThe operations that differ from the ASI-V as the relate to the TOC-VCP model are described here.

2.4 WP OperationThe operations that differ from the ASI-V as the relate to the TOC-VWP model

are described here.

2.1 CS Operation

162.1.1 TC Blank Check Measurement

2.1 CS OperationThis section describes measurement operations using the 8-Port Sampler. These operations are not covered in the TOC-VCSH/CSN user manual. Operations that are not described here are the same as those described for the autosampler (ASI-V). Refer to the applicable item in the TOC-VCSH/CSN user manual for more information.

2.1.1 TC Blank Check Measurement

The measurement procedures described here differ from those using the ASI-V autosampler. The water collection port is different than the one used with the ASI-V. Refer to Section 3.1.17.2 TC Blank Check Analysis in the TOC-VCSH/CSN user manual for further details.

Single 8-Port Sampler

Insert the TOC-V offline port sample tubing into a container with at least 200 mL of water.

Two 8-Port Samplers

Insert the sample tubing from port No. 9 of 8-Port Sampler 2 into a container with at least 200 mL of water.

2.1.2 8-Port Sampler Measurement

Unlike the autosampler, the 8-Port Sampler is not restricted to a fixed sample vial size. The OCT-1 8-Port Sampler can accommodate sample containers of various sizes. The procedures described here are related to sample preparation, sample loading and high sensitivity measurement as they relate to the different sample containers. Refer to Section 3.3 Analysis with the Autosampler in the TOC-VCSH/CSN user manual for more information.

2.1.2.1 Sample Preparation

Type of Sampler Container

There are no restrictions on the type of sample containers that can be used with the 8-Port Sampler. It is only necessary that the containers be placed so the sample tubing from the various ports can be inserted directly into the containers.

Note: Wash all sample containers with an appropriate laboratory detergent, and rinse them thoroughly with water before using them for the first time. OCT-1

2.1 CS Operation

CS2.1.2 8-Port Sampler Measurement

Loading the Sample

Although it is possible to perform measurement of a sample using the 8-Port Sampler, while the container open, in the following situations, it is necessary to seal the sample container.

1 When performing IC measurement

2 When performing POC measurement

3 When performing measurement of low concentration samples (e.g., 10 mg/L)

4 When performing measurement of alkali samples of pH 7 or higher

5 When performing measurement of samples containing volatile organic carbon compounds

6 When the number of samples is so great as to require a long measurement time

7 When performing measurement of standard solutions

Note: If the sample container openings are not sealed in the situations listed above, measurement values may be influenced by such factors as absorption of atmospheric CO2, contamination with carbon containing substances, and evaporation of TOC constituents from the samples.

Sealing the Sample Containers

Sample containers may be sealed using commercial sealing films such as Parafilm. It is also possible to pierce the lid of the container and insert the sample tubing into the container through this opening.

Note: In either case, wash the container with a laboratory detergent, and rinse it thoroughly with water before use. 17OCT-1

2.1 CS Operation


Sealing Procedure Using Parafilm

1. Cut the Parafilm into approximately 25 x 25mm (1inch x 1inch) squares.

2. Place a Parafilm square over the opening of the vial, and stretch it to seal it to the edges of the vials.

3. Press the edges down so that they wrap around the outside of the vial.

CS2.1.2 8-Port Sampler Measurement

2.1.2.2 High Sensitivity Using the 8-Port SamplerIf samples such as purified water or ultra-pure water, having a TOC concentration of 100ppb or less, are to be measured using the 8-Port Sampler, it is necessary to consider the following precautions associated with high sensitivity analysis. Refer to Section 3.3.1.4 High Sensitivity Autosampler Analysis in the TOC-VCSH/CSN User Manual for more information.

1 NPOC analysis is recommended because TOC (TC-IC) analysis tends to have a greater variation in measured values than NPOC. This is because IC often accounts for a significant portion of the TC, and the errors in the two values are additive using TOC (TC-IC) analysis. This affect significantly influences TOC analysis.

2 For measurement of standard solutions for creating calibration curves, fill well-washed containers with standard solutions to about 5-10 mm from the top of the container, and immediately seal each container. When placing the container below the 8-Port Sampler, handle it carefully to avoid the standard solution contacting the sealing surface. Low-concentration standard solutions must be prepared each time they are used.

3 To ensure that the peaks are stable for generating the calibration curve, perform 4-5 injections using the same analysis parameters prior to performing the calibration curve analysis. For example, to generate a 400ppb calibration curve, set 400ppb as the 1st standard solution concentration, and enter 1 as the container number. Actually place a 0ppb solution in the container for port No. 1. The objective at this point is not to generate a calibration curve, but to inject water using the same injection volume that will be used to generate the calibration curve. This not only stabilizes peaks but also thoroughly washes the sampling needle with purified water.

In the 2nd row of the settings screen and using the same calibration curve number as above, set the analysis parameters for 0ppb and 400ppb. When sample measurement starts, the calibration curve to be used will be created with the correct standard solutions. 19OCT-1

Note: Wash all sample containers with an appropriate laboratory detergent, and rinse them thoroughly with water before using them for the first time. 21OCT-1

2.2 WS Operation


Loading the Sample

Although it is possible to perform measurement of a sample using the 8-Port Sampler, while the container open, in the following situations, it is necessary to seal the sample container.

1 When performing IC measurement

2 When performing POC measurement

3 When performing measurement of low concentration samples (e.g., 10mg/L)

4 When performing measurement of alkali samples of pH 7 or higher

5 When performing measurement of samples containing volatile organic carbon compounds

6 When the number of samples is so great as to require a long measurement time

7 When performing measurement of standard solutions

Note: If the sample container openings are not sealed, measurement values may be influenced by such factors as absorption of atmospheric CO2, contamination with carbon containing substances, evaporation of TOC constituents from the samples, etc.

Sealing of Sample Containers

Sample containers may be sealed using commercial sealing films such as Parafilm. It is also possible to pierce the lid of the container and insert the sample tubing into the container through this opening.

Note: In either case, wash the container with a laboratory detergent, and rinse it thoroughly with water before use. OCT-1

2.2 WS Operation

WS2.2.2 8-Port Sampler Measurement

Sealing Procedure Using Parafilm

1. Cut the Parafilm into approximately 25 x 25mm (1inch x 1inch) squares.

2. Place a Parafilm square over the opening of the container, and stretch it to seal it to the edges of the container.

3. Press the edges down so that they wrap around the outside of the container.

2.2.2.2 High Sensitivity Using the 8-Port SamplerIf samples such as purified water or ultra-pure water, having a TOC concentration of 100ppb or less, are to be measured using the 8-Port Sampler, it is necessary to consider the following precautions associated with high sensitivity analysis. Refer to Section 3.1.14.1 High Sensitivity Analysis in the TOC-VWS User Manual for more information.

1 NPOC analysis is recommended because TOC (TC-IC) analysis tends to have a greater variation in measured values than NPOC. This is because IC often accounts for a significant portion of the TC, and the errors in the two values are additive using TOC (TC-IC) analysis. This affect significantly influences TOC analysis.

2 For measurement of standard solutions for creating calibration curves, fill well-washed containers with standard solutions to about 5-10 mm from the top of the container, and immediately seal each container. When placing the container below the 8-Port Sampler, handle it carefully to avoid the standard solution contacting the sealing surface. Low-concentration standard solutions must be prepared each time they are used.

3 To ensure that the peaks are stable for generating the calibration curve, perform 4-5 injections using the same analysis parameters prior to performing the calibration curve analysis. For example, to generate a 400ppb calibration curve, set 400ppb as the 1st standard solution concentration, and enter 1 as the container number. Actually place a 0ppb solution in the container for port No. 1. The objective at this point is not to generate a calibration curve, but to inject water using the same injection volume that will be used to generate the calibration curve. This not only stabilizes peaks but also thoroughly washes the sampling needle with purified water.

In the 2nd row of the settings screen and using the same calibration curve number as above, set the analysis parameters for 0ppb and 400ppb. When sample measurement starts, the calibration curve to be used will be created with the correct standard solutions. OCT-1
