Ph. Eur. Monograph 1317: A Means of Improving the Resolution Between Acetaldehyde and Methanol in the Limit Test for 96% Ethanol
The European Pharmacopoeia has published a gas chromatography method for the purity analysis of 96% ethanol (Ph. Eur. Monograph 1317; Supplement 10), which stipulates that the peaks for residual amounts of acetaldehyde and methanol be resolved from one another with a minimum resolution factor of 1.5. Acetaldehyde and methanol can be challenging to resolve from one another within the confines of this method, however baseline resolution is imperative for the purity analysis of ethanol. The Ph. Eur. method specifies the use of a poly[(cyanopropylphenyl)- (dimethyl)]siloxane capillary GC column, for which the Zebron™ ZB-624 has been demonstrated to suitably resolve acetaldehyde from methanol
