1.	Which of the following is the expression for Eddy diffusion in the column, if ‘γ’ represents obstruction factor, ‘dp’ represents particle diameter, ‘DM’ represents Solute diffusion co-efficient and ‘λ’ represents function for packing uniformity?(a) λ dM(b) 2 γ DM(c) DM γ(d) λ/dMThis question was addressed to me in an interview for internship.Query is from Column Efficiency and Column Resolution in chapter Chromatography of Analytical Instrumentation
Answer» Right option is (a) λ dM For explanation I would SAY: EDDY diffusion is given as, A = λ DP. It is also CALLED MULTIPATH term.
