I have about 40 GC/MS chromatograms and want to find the similar peaks.
If you are expert in reading GC-MS chromatogram then you can easily identify it. If not then identify on the basis of alkane mixture to calculate RRI of each peak. For characterisation match with previous literature or with Adams book or NIIST library.
gudluck
:)
I have the retention index of all peaks. Are they using for comparison? For each peak I have three hits from NIST. which should I consider? Is it right to prepare a table of retention index to find the similar peaks? I have 40 chromatograms and each one has about 30 peaks. I want to find a profile of peaks for my sample.
You can identify the similar peaks on the same retention time of the samples. At first, you must know the peak of standard samples, you can compared the same retention time of the comparative and standard samples. And then you accumulate integral of the peak to gain the total area of the peak. You can through calculate the area between comparative and standard samples to analysis the concentration of the comparative samples. The specific organics have a given retention time.
