Workflow: Initial Operation
/ Cleaning
7.1 Using the Cleaning Mode
The device can get contaminated for several reasons. Contaminations show up
as additional peaks next to the RIP even when no measurement is running and
the system is only connected to the drift gas and carrier gas nitrogen source. If
this is the case start the cleaning mode.
Before using the device for the first time or after being disconnected from the
nitrogen source for more than one day it must be cleaned to ensure proper
operating conditions.
An appropriate cleaning period duration must be chosen depending on how long
the device was switched off and on the extent of contamination. It is
recommended to clean the device for ~15 hours before operating it for the first
time. It is recommended to use High Flows during Cleaning.
7.2 Workflow
Workflow 2: Cleaning Mode
The cleaning process must be completed ~2 hours prior to any
measurement so that the internal components can cool down to the
required temperatures.
