VOCs method on GC-MS

[nicolo.bellora]

Hello everyone,

I'm developing a method for VOCs in plastic film using headspace coupled with GC-MS. I have some difficult because is the first time that i use an headspace.
I'm using 150°C for 30 min for samples incubation in headspace but i dont know which is the best temperature ramp on GC oven.

Someone had experiences in VOCs analysis?
Thanks in advance

I would start with an application note from your instrument or column vendor. You haven't specified which VOAs/instrument/column etc. Also, what are your headspace conditions going to be? All these things matter.
