What's the problem with these TICs?

Discussions about GC-MS, LC-MS, LC-FTIR, and other "coupled" analytical techniques.

Seeni,

I don't know the thermo software (yet - I'm starting to use a MAT 95, so that will change), but the GC/MS software I've encountered from tohter vendors allows you to set some kind of detection threshold - and changing that should allow for more or fewer peaks to be found. And, once you have found many peaks, there should be a way of selecting specific target compunds for reporting. So, you should be able to find many compunds in a mixture and then report relative concentrations for a selected list.

Again if you need TIC information and you do not have a way to get it out of your software, I know you can get it out of AMDIS. It has reporting and target analysis capabilities. Worst case it will get you almost all the way there and you take a list of peaks and deconvoluted areas to a spreadsheet to get relative percents.

You will have to do some exploring. But, it will get you to wonderful places you never dreamed of.

Good luck.

Don
Dear Don,
Thanks a lot for your valuable input. I got it now. the thing is i have worked with standard concentration of 25 ppb. When i injected 1 ppm all peaks are there in the TIC. Thank you.

Regards

Seeni
