1.	Which of the following is not an advantage for the conversion of packed columns into wide bore capillaries?(a) Longer retention times(b) Longer life(c) Higher efficiency(d) Greater inertnessThe question was posed to me by my college director while I was bunking the class.My doubt stems from Gas Solid Chromatography topic in portion Chromatography of Analytical Instrumentation
Answer» Right answer is (a) LONGER retention times Best EXPLANATION: Wide BORE capillary has a shorter retention time. It is an advantage. It is undesirable to have a longer retention time.
