I'm quite new about this GC world but I need to measure Tetrachloroethylene (PCE) and Trichloroethylene (TCE) mixture (or one by one) in GC. I tried several times with MS and FID but I got meaningless results, I still do not have a calibration curve. Samples for MS were prepared with hexane extraction from aqueous solutions and aqueous samples diluted from stock solution directly injected to GC/FID. We have headspace unit but out of use and I should immediately measure them with what we have. Am I wrong about sampling of these chlorinated solvents if yes could you please inform me about sample preparation of PCE,TCE for MS and FID or I use wrong column type with wrong method ?
The FID column is Elite-FFAP (30m,0.32mm,0.25um)-(40 to 250 degree C) and
MS column is DB-5MS (30m,0.250mm,0.25um)-(-60 to 325/350 degree C) also Elite-5MS column we have.
thank you in advance
