Which of the following is not an advantage of gas-solid chromatography

1.	Which of the following is not an advantage of gas-solid chromatography?(a) Increased column life(b) Can be used for separation of rare gases(c) Leads to semi-permanent retention of the analyte(d) Ability to retain some components that cannot be easily retained by other gas chromatography methodI have been asked this question in an online interview.This intriguing question originated from Gas Solid Chromatography topic in division Chromatography of Analytical Instrumentation
Answer» Correct option is (c) Leads to semi-permanent retention of the ANALYTE To EXPLAIN I would say: Gas-solid CHROMATOGRAPHY leads to semi-permanent retention of the analyte. Hence, it is USED for limited applications.
