Answer #1

Flame ionisation detector is mass sensitive.
The flame ionisation detector (FID) is the automotive emissions industry standard method of measuring hydrocarbon (HC) concentration. The sample gas is introduced into a hydrogen flame inside the FID. Any hydrocarbons in the sample will produce ions when they are burnt.
FID measurements are often labelled "total hydrocarbons" or "total hydrocarbon content" (THC), although a more accurate name would be "total volatile hydrocarbon content" (TVHC), as hydrocarbons which have condensed out are not detected, even though they are important for e.g. safety when handling compressed oxygen.
Hence FID i.e. flame ionisation detector ia considered as carbon counter as it is used to detect the number of hydrocarbon present in the sample.
