i need to change an established PAH method. The reason is that i have to analyze four more PAHs. These new PAHs have a higher evaporation temperature and i cannot find them with the method we actually use.
- Benz[a]anthracene
- Benzo(b)fluoranthene
- Benzo[a]pyrene
- Chrysene
- Dibenz[a,h]anthracene
- Indeno[1,2,3-c,d)pyrene
- Benzo(k)fluoranthene
- Benzo[g,h,i]perylene
GC: Agilent 7890A
MS: 7000A Triple Quad
coupled with a CIS and TDU from Gerstel.
As i am new to GC MS MS (or the system we use) i am a little shy/careful to just change some of the parameters like source or cis temperature, cis injection speed and so on.
Does anyone already have an established method or know what i could change or try ?
I can provide any additional information
Thanks a lot
