Rapidly Analyze a Wide Range of Glycol Ethers by GC–MS

Chromatographic conditions were developed for a fast GC-MS glycol ether analysis on the Rxi®-1301Sil MS column. This cyanobased thin film column provides better resolution and faster run times than the thick film cyanopropylphenyl-type columns commonly used for speciation of the glycol ethers. The glycol ethers are high production volume industrial chemicals that often occur as complex mixtures of isomers. The Rxi®-1301Sil MS column is uniquely matched for the separation of these isomers while still producing narrow and symmetric peaks for the low molecular weight ethylene glycol ethers.
