1.	Which of the following components cannot be retained by gas-liquid columns but can be separated by using gas-solid chromatography?(a) Formaldehyde(b) Hydrogen sulphide(c) Benzene(d) Carbon dioxideI have been asked this question in an interview for internship.This interesting question is from Gas Solid Chromatography in chapter Chromatography of Analytical Instrumentation
Answer» Right answer is (B) HYDROGEN sulphide To elaborate: Hydrogen sulphide cannot be RETAINED by gas-liquid columns. It can be SEPARATED using gas-solid CHROMATOGRAPHY.
