Peak Simple 101

[@alihussainmota]

This is an excellent tutorial. Extremely clear and got me up and running in no time. Thank you!!!

how do you detect a component from their peaks?

[@analyticalservices8058]

with the peak retention time

How can i know the response factor for gases with peaks??

[@SRIGCTraining]

You would calibrate using a known amount of sample(s), and then use that as your calibration curve. If you wanted know the exact response factor for, let's say Nitrogen, you could inject 1ng of nitrogen and see that you get a response of 1 area count. From this we can say that each ng of nitrogen == 1 area count. This only works if the response is linear, and it can vary due to the detector, carrier gas, and detector gain. If you have any questions give us a call at [phone]

SRI GC Training Thx for replying.. Can i use the area normalization method to calculate the weight for components???

[@SRIGCTraining]

You could. You would still have to know where the peaks come out, and what your sample is made of. I haven't watched this whole video in a while and don't currently have time to scroll through it right now. Are you talking about the norm area %? Or a different specific method not related to the video? If it is something in the video feel free to reply with the time it appears in the video, so I can answer your question better.
