Peak Area units in Chromeleon 7.2 for GC/ECD

[whdees]

hello all,

I just got a new GC toy to play with, a dual column, dual ECD Trace 1300, using Chromeleon 7.2 to acquire and process the data for herbicides, pesticides, etc. So far, I am finding it to be friendly, intuitive, in general quite well done - but one thing has me totally baffled. As a long-time Chemstation guy, I am used to seeing peak area integrations as some pretty darn big values, from several hundred thousand to several million being typical peak areas... CDS 7.2 is giving me peak areas in decimal fractions, with the units being kHz*min. I have looked, but can't find a way to change this, and these peak areas don't really tell me much... anybody have any insight into this?

maybe I just need to mentally shift gears...I'll figure it out.

thanks!

Hi whdees,

This is quite an easy one to tackle...

Double click on the header of the Peak Area column within relevant table. A pop-up will then appear (properties of the column). Within the formula, you are able to perform arithmetic functions, so simply multiple your peak area by the desired correction.

For example.
Peak.Area*60000

Hope this helps

I actually did consider that, but now I'm thinking maybe I should go with the flow until I know the system better...I've only been playing with it for a week. Once I have some clue what I'm doing, I may make that change, or just roll with it as is. I do appreciate your suggestion, and I'm sure I'll have plenty more stupid questions in the near future...thanks!
