(TOC) Rinsing the Flow Lines (TOC-1000e)

• Rinsing the Online Flow Line

NOTE: Rinsing is normally not necessary because the instrument is designed so that water passes through even when measurement is not being performed.

 

1. Press  - [Maintenance].

2. Press [Machine Sequence].
  The [Machine Sequence] screen appears.
  Make sure that the sample liquid is flowing to the online side.

3. Press [Flow Sequence-Main Unit].

   

  NOTE: Note that rinsing cannot be stopped once the button is pressed. It takes approximately 5 minutes to complete.

  Flow line rinsing starts automatically.

4. The [Machine Sequence] screen is displayed when rinsing is finished.
  The rinsing process is complete.
  NOTE: Perform rinsing multiple times if necessary, such as when a high-concentration sample was measured recently.

 

• Rinsing the Vial Sampler Flow Line

1. Press  - [Maintenance].

2. Press [Machine Sequence].
  The [Machine Sequence] screen appears.

3. Prepare four vials and load them into the vial sampler.

  NOTE:

  • See "Using the Vial Sampler" before loading the vials into the vial sampler.
  • Use pure water with a TOC of less than 100 μg/L. "Preparing the Blank Water".

4. Press [Flow Sequence-Vial Unit].

   

  NOTE: Note that rinsing cannot be stopped once the button is pressed. It takes approximately 20 minutes to complete.

  Flow line rinsing starts automatically.

5. The [Machine Sequence] screen is displayed when rinsing is finished.
  The rinsing process is complete.
  NOTE: Perform rinsing multiple times if necessary, such as when a high-concentration sample was measured recently.
