A Means of Improving the Resolution Between Acetaldehyde and Methanol in the Limit Test for 96% Ethanol (Ph.Eur.1317)

Abstract:

Working within the adjustments allowed by the European Pharmacopeia (Ph.Eur.) for this GC method, the Zebron ZB-624 column was demonstrated to provide the separation power required for the quantitative determination of acetaldehyde and methanol in 96% Ethanol. The improved resolution demonstrated is well above the minimum value (1.5) that is stipulated within the monograph, affording the analyst leeway for fluctuations that may arise in GC instrument performance.
