Processing TPH C6-C9 Through LabSolutions/Shimadzu (GC-MS)
Posted: Tue Jul 25, 2023 8:34 am
Hi All,
Some background: Our lab usually runs Volatiles TPH's on an agilent GCMS through headspace. This is then analysed through chemstation using a SCAN method that integrates from C6 through to C9 with one baseline.
The Problem: I am having an issue setting this up through Shimadzu GCMS (NEXIS GC-2030, GCMS-TQ8050 NX) and the LabSolutions software. The actual run is fine, all peaks are coming through nice and sharp.
I have been able to set up a program inside the qualitative parameters window, using the "PEAK DETECT", "PEAK TOP", "PEAK END". When i choose a chromatogram and simulate this I am getting the single baseline integrating from C6-C9 perfectly. BUT I am unsure how to make this program apply to a batch of calibration standards (we run 20 ppb to 2000 ppb), and give me a quantified result.
I am fairly new to building a process method from scratch, mainly just prep samples and process/analyse, so I apologise if I am missing any obvious information that would make this question easier to answer.
Any help would be greatly appreciated.
Kind regards,
Lochlan
