摘　　要：提出了气相色谱测定醛、酮产品中水分的方法。样品中水分经PLOT-Q毛细管色谱柱分离,热导检测器（TCD）测定。检出限（3N/S）为0.0001%。在0.025、0.508、0.1025%三个浓度水平进行加标回收试验,回收率在97.1%~101.5%,测定的相对偏差（n=5）在3.1%~5.2%之间。A method of determination of water content in aldehydes and ketones by GC was developed. Water was separated from other components through PLOT - Q capillary column, analyzed by GC - TCD and quantified by external standard method. Detection limits（3N/S） was 0.0001%. Tests for recovery were made at the concentration levels of 0. 025,0. 508 and 0. 1025%. The recovery was in the range of 97.1% ~ 101.5% and the RSD was in the range of 3.1% -5.2%.
