Shut down procedure

For Cations:

1. Close the RUN program.
2. Turn off the column oven (also turns off the pump and other items).
3. Turn off the DG1310 degas box.
4. Turn off the helium tank.
5. Turn off the deionized water Teflon valve.
6. Process your data with the BATCH program, with or without checking baselines and so on using the OPTIMIZE program.
7. Shut down the computer and turn off the printer.

For Anions:

1. Close the RUN program.
2. Turn off the column oven (also turns off the pump and other items).
3. Turn off the conductivity detector.
4. Turn off the helium tank.
5. Turn off the deionized water Teflon valve.
6. Process your data with the BATCH program, with or without checking baselines and so on using the OPTIMIZE program.
7. Shut down the computer and turn off the printer.

For Silica:

1. Turn off the PCR reaction loop heater (hot black box).
2. Depressurize the PCR chamber.
3. In the RUN program, load your silica method.
4. Disconnect the black connector at the top of the PCR chamber. Connect it to a 10 ml syringe (top drawer) and inject 10 ml of DI water through the system. This flushes the tubing of the PCR solution, which can clog the tubing after awhile with very-hard-to-dissolve precipitates.
5. Close the RUN program.
6. Turn off the column oven (also turns off the pump and other items).
7. Turn off the absorbance (UV-Visible) detector
8. Turn off the helium tank.
9. Turn off the deionized water Teflon valve.
10. Process your data with the BATCH program, with or without checking baselines and so on using the OPTIMIZE program.
11. Shut down the computer and turn off the printer.
