“…In GC, a ame ionization detector (FID) has the merits of high sensitivity, precision, and reproducibility for most hydrocarbon compounds. [97][98][99] Remarkably, in complex matrices such as soil or atmospheric PM, to prevent all organic molecules from giving a response (such as aliphatic compounds and lipids), a very intensive clean-up is required before the sample is analyzed. Moreover, some researchers have attempted to perform BTEX and PAHs determinations using a barrier ionization discharge detector (BID) and a photoionization detector (PID).…”
