You used a flame ionization detector(fid) in this experiment.
(a) explain how a fid detector works.
(b) another common detector for gc is a thermal conductivity detector (tcd). describe how a tcd works.
(c) both the fid and the tcd are classified as "bulk" detectors. what does this mean?
(d) what are the advantages and disadvantages of a fid and a tcd?
