Chromatography Forum

Dear all,

we would like to run a sequence automatically after Chemstation start not having to press F6 to start it.

We have done some tests by including LoadSequence and RunSequence in the user.mac file but it gives an error (it looks as if the sequence is started twice).

Does anyone now how we could solve this problem?

Thank you in advance for your help,

Would starting the sequence from the ChemStation scheduler solve your problem? You could start the sequence at any time of the day, on any date, automatically using the scheduler.

It would not solve the problem because we are trying to consider the situation where there is an electrical fault, then electricity comes back and:

- The PC restarts automatically
- Chemstation restarts automatically
- The sequence starts... (this is what we would like to do), whatever the time it is.

Do you know what I mean? Could it be possible?

Thank you!

Unless the power cut is so considerate as to happen when the GC (or LC) is in post-run you will have the remnants of the previous sample sitting in a column that is not properly equilibriated when Chemstation fires up again and makes the next injection. The resulting chromatogram is likely to look quite interesting.

We have found a way to do what we wanted:

we create a CP and request from it (through a macro) the loading and running of the desired sequence (we introduce CPStart and CPRequest in user.mac). We think it works like this. We don't terminate the CP, will it be a problem?

It's true that the first chromatogram will be wrong, so I'm thinking about the possibility of running as first (and atomatically started) sequence one to flush columns and empty samples loops, would it be a good option?

Thanks for yours answers,

I can imagine that QC auditors might want to see a coupple of standards run before the samples start again?
