Calculating the headspace concentration -

2018/10/26 · 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.
