Follow the instructions in this section to turn on or turn off the detector gas flow.
CAUTION
Escaping Gas
Gas can escape from open gas connections when the detector gas flow and/or the gas supply is turned on. The escaping gas can pose a health and safety risk.
NOTICE
Detector Gas Flow and Pump Flow
Improper handling of detector gas flow and pump flow start and stop can damage the detector. Observe the respective order of steps:
Turning On the Detector Gas Flow
Make sure that you observe the site requirements for the gas supply. See Gas Supply Requirements.
Make sure that the following prerequisites are met:
The nebulizer is installed.
The components in the gas flow path are properly connected.
The protective cover of the gas filter assembly is installed.
Turn on the gas supply to the detector. Observe the Gas specifications for the gas supply pressure. See Performance Specifications.
Turn on the gas flow in the detector using the GAS button on the keypad of the detector or using the chromatography data system.
Close the detector doors.
Wait at least 5 minutes and only then turn on the pump flow, if needed.
Turning Off the Detector Gas Flow
This procedure depends on whether the pump flow is on.
Pump flow is off | Pump flow is on |
---|---|
Turn off the gas flow in the detector using the GAS button on the keypad of the detector or using the chromatography data system. | 1. Turn off the pump flow. 2. Wait at least 5 minutes and only then turn off the detector gas flow using the GAS button on the keypad of the detector or using the chromatography data system. |
