Poor Recovery for residual solvents by GC-FID-HS
Working std 1ml in 20ml HS Vial. The areas were arround 400 (EtoH), 200 (Acetone and IPA) and 12 (DCM). In the spiked sample the recoveries for acetone IPA and DCM were arround 70-80%. I compared the volume to be tested 2ml and 5ml in HS vial the areas are good in working std but recoveries were still like 70-80%. Please give me some ideas. Thanks

Calculating the headspace concentration - Chromatography Forum
Oct 10, 2018 · Heat the vial above the boiling point of everything in the vial (solvent must boil less than the ndma in this case). Use a heated gas-phase syringe to make your injection. In theory, if you have 22 µg of ndma in a 22 mL headspace vial and you inject 1 mL of gas from the vial, then you'd be injecting 1 µg of ndma into the gc.
