HELP: HPLC CHEMSTATION SOFTWARE
Caobin Zhu
Hi to all,
I have a strange situation. Recently I started to use HP HPLC
chemstation software. My supervisor lost the software manual and I am
not sure if we are using the software the right way. The problem is
that when I load a file back again which has been integrated before, I
LOST EVERY INTEGRATION DETAIL! This is terriable!
Any help would be greatly appreciated.
By the way, we are using Windows 95 with 16MB ram. the LC
chemstation software is rev. A.04.01.
Thanks.

In article , cao...@flash.net says...
separatly from the integration parameters. You must be sure to save your
methods (they contain the integration parameters).
Before you bring up a data file, the method you used to integrate should be
loaded first. In order to see everything, you need to reintegrate to see all
the details on the screen. Printing out hard copies as a reference is not a bad
idea. I have had too many computerized instruments crash and would have lost
all data if I didn't do that.
You should also contact HP - manuals are cheap (~$20 - $70).

Hi to all,
Thanks for many peple's reply to my question. However I'd like
to make this question more specific (or clearer if it is not clear
last time and I am sorry for that if that is the case).
My problem is that AFTER I MADE EVERY MANUAL INTEGRATION TO
the LC chromatogram, and when I reload THAT FILE BACK, then ALL THAT
INTEGRATION IS LOST! I tried saving the method but still it does not
help. Any help would be greatly appreciated.
Thanks again.

infomation that I had rec'd it IS supposed to save the manual
integration events....some people I work with do pcb's and are using an
older system Chemstation that you have to manually log the integration
events and then separately save this to a file yourself. I would expect
that your manual integrations are saved with the data file, not the
method file...? try looking in the data file directory and see if there
is a file wwith date of manual integration( different than the
acquisition time
Otherwise I would guess that there is either a sofware bug. or you may
need to save or turn on saving integration events
Does the online haelp give any reference to saving integration events?
Also just loading the data file may not be enough - you may also have to
load the manual integration events file
Well that's about all my guesses - I would try to find out from HP
software support centre if there is nothing in the online or CD help
files.

Cutting the salaries of the H? Board of Directors by 10% could result in

Hi Scott
This doesn't make sense...that the manual events are saved with the
method and not the data file. If you are doing manual integration of a
complex chromatogram or crappy separation then each chromatogram is
probably going to need different baseline events and these should be
saved with the data file to later re-integrate if needed.
I could understand in a perfect world running standards or very similar
samples that the manual integration events could be saved with the
method and applied to a batch or sequence of data files.
If true this could be a major problem for anyone doing pcb or any other
mixed matrix or dirty samples at the lowest concentration levels.
