1.	Which of the following is not a desirable feature of the ovens used in gas chromatography?(a) It must have a fast rate of heating(b) Power consumption should be kept low(c) It must have maximum thermal gradients(d) It should have proper insulationI had been asked this question during an online interview.I want to ask this question from Gas Chromatography topic in section Chromatography of Analytical Instrumentation
Answer» CORRECT choice is (c) It must have MAXIMUM thermal gradients Easiest explanation: The OVENS used in gas CHROMATOGRAPHY must have maximum thermal gradients. The TEMPERATURE must be uniform over the whole column.
