1.	In gas-liquid chromatography, when films are used in the interior of the capillary column, then what is the value of Eddy diffusion?(a) Greater than 1(b) Less than 1(c) Zero(d) Less than zeroThe question was posed to me in an internship interview.Origin of the question is Column Efficiency and Column Resolution topic in chapter Chromatography of Analytical Instrumentation
Answer» The correct OPTION is (c) ZERO Easy explanation: In gas-liquid chromatography, when films are used in the interior of the CAPILLARY column the value of EDDY DIFFUSION (A) is zero. To minimize A, diameter of packing should be small and uniform.
