1.	Which of the following is the disadvantage of coiled or helical shaped packed chromatographic column?(a) It cannot be packed uniformly(b) It cannot be repacked easily(c) It is not compact(d) It is not easy to heat it evenlyI have been asked this question in my homework.This intriguing question comes from Gas Chromatography in section Chromatography of Analytical Instrumentation
Answer» Right ANSWER is (b) It cannot be repacked easily For explanation: The DISADVANTAGE of COILED or HELICAL shaped packed chromatographic column is that it cannot be repacked easily. It is compact in size and can easily be HEATED in an even manner.
