1.	What is the drawback that occurs in using gas chromatography for amino-acid analysis?(a) Costly(b) Cannot be used for proteins or polypeptides(c) Slow process(d) Complex in operationI had been asked this question in semester exam.The above asked question is from Amino-Acid Analysers in division Chromatography of Analytical Instrumentation
Answer» Correct OPTION is (b) Cannot be used for proteins or polypeptides The best EXPLANATION: GAS CHROMATOGRAPHY cannot be used for proteins or polypeptides. Further, accuracy is lost while CONVERTING amino-acids into the gaseous phase.
