| Abstract |
Porous polymer packings have been used successfully in many applications of direct aqueous injection gas chromatography. The authors have expanded the use of aqueous injection to the quantitative analysis of 68 alcohols, acetates, ketones, ethers, sulfides, aldehydes, diols, diones, nitriles and amides on a glass column packed with unmodified Tenax GC using a flame-ionization detector. Analysis of single- and multi-component mixtures, accurate standard preparation, assessment of analytical errors, limitations of the method and problems encountered are discussed. Peak ghosting and tailing were not serious problems. The analytical error between chemical classes expressed as the coefficient of variation between duplicate samples ranged from 0.81% for nitriles (n=3) to 7.09% for ethers (n=5). The method described is fast, precise and accurate, requires little sample preparation and is applicable to a wide variety of compounds. |
