I am working on developing a method for quant some volatile organic compounds on GCMS. My way is like that;
For example; benzen limit is 10 ppm. I prepare 2,5 - 5 - 10 - 25 - 50 ppm calibration point.
We taking organic compounds with a activated charcoal tube and its have 150 mg activated carbon in it.
I break the tube and take the activated charcoal on a tube and add 5 mL of methanol (my solvent that i am using for all method). Mix them for 30 min. After 30 min. i take 1 mL to gc vial from 5 mL solution and give the GCMS to read.
Then when i quant the sample is my dilution factor 5/150 or 5/1 ?
