摘要: Abstract Column overload causes errors in the estimation of equivalent chain lengths (ECLs) fatty acid methyl esters (FAMEs), and extent these on fused-silica open tubular columns has been investigated. Load limits for several common FAMEs were accurately determined utilizing a synchronized, rapid automatic liquid sampler. The findings applied to obtain estimates ECLs range C 18 unsaturated precision (repeatability) about ± 0.001 ECL units. Three stationary phases, DEGS, SP-2330 Supelcowax 10, studied, each at three temperatures.
