1.	Which of the following is the disadvantage of nitrogen, which can be used as carrier gas in gas chromatography?(a) Dangerous to use(b) Expensive(c) Reduced sensitivity(d) High densityThe question was asked during an interview.This intriguing question comes from Gas Chromatography in chapter Chromatography of Analytical Instrumentation
Answer» CORRECT option is (C) Reduced sensitivity For explanation I would say: Nitrogen has reduced sensitivity. It is still one of the commonly USED carrier gas in gas chromatography.
