Preparation Of Measurement - Siemens MicroSAM Operating Instructions Manual

Note
Types of solenoid valves
The membrane valve functions are controlled by solenoid valves. Two types of solenoid
valves are used: open when deenergized and closed when deenergized.
Closed when deenergized: MV2 - Sample, MV4 - Injection
Open when deenergized: MV1 - Flush loop, MV3 - Back flush
Open when deenergized: MV1 – Flush loop_1, MV5 – Flush loop_2
Result
The result of the measurement is e.g. a chromatogram with time switching points on detector
TCD 2. This chromatogram shows the difference in the two procedures (live and eLive)
between the switching points t
