problems with ChemStation B.03.02

[VasaCh]

Hello,

I have 2 different problems with ChemStation:

1) Area labels - when I manually integrate some peak, information on peak area appears - I do not know how to eliminate this information even if I know how to remove peak name or RT (in Signal Options)

2) Integration settings - when I want some chromatogram to Auto Integrate, messages "too few peaks found to optimize peakwidth" and "No peaks detected at optimum Signal-to-Noise" appears - I tried to reconfigurate Integration Events but it did not help.

Thank you for any help.

On the B.03.02 CD2 in x:\UCL\LCUCL\Macros\9 is a macro, 'tmanann.mac' which toggles the manual integration annotation on/off. See the Readme.txt file for instructions.

You didn't mention if this is GC or LC, or which detector is used. It sounds more like a chromatography problem, is there a better wavelength? Can you increase sample size, etc. You need to get peaks big enough to recognize. Perhaps a good bake out of flushing of the system would reduce the background noise?

Many thanks for your reply.

1) Unfortunately, I have not found 'tmanann.mac' file, because I don't have installation CDs - I installed it from flash disc - it is ChemStation for GC-FID analysis and the installation folder doesn't contain folder UCL and others. I am enclosing link of picture to see which folders are there - on the left side, on the right there is folder with already installed ChemStation.

2) It helped to change system from Win XP to Win 7 - It was not chromatography problem, because the same method and data file functioned in lab but not at another notebook at home.
