We have microGC in the lab, equipped with Buckflush Column module 20 m MS5 (Channel 1) and Column module 10m PPU (Channel 2). As carrier gases Ar and He are used, respectively in Ch 1 and Ch 2. I have problem to get GC „ready“. Strange thing is, in some days it works properly, some other days not.
After loading the method and waiting for set temperatures, the General status overview is still „Not Ready“ and the GC does not allow to start analysing (even the status for columns, injectors and detectors show „ready“ ). In Service Tool box, in Channel Status page I can see two red values , TCD bridge volt ( 0.05; -0.06) for Ch 2. Could you please tell what can be the problem and how to solve it?
