1.1 This test method describes the spectrophotometric determination of total aldehyde content in mono-, di-, and triethylene glycol (MEG, DEG, and TEG). Alkoxyalcohols (hemiacetals), if present, are co-determined, whereas dialkoxyalkanes (acetals), if present, are not. The results provide a measure of the purity of the sample with respect to total aldehyde content.
