High Performance Liquid Chromatographic Determination of N-Methyl-2-pyrrolidone in Water 作者： Darryl A. Frick 作者單位： 1PPG Industries, Inc., PA 刊名： Journal of Liquid Chromatography & Related Technologies, 1983, Vol.6 (3) 來源數(shù)據(jù)庫： Taylor & Francis Journal DOI： 10.1080/01483918308076060 英文摘要： N-Methyl-2-pyrrolidone was determined in water using High Performance Liquid Chromatography. A determination required less than 10 minutes using an octadecyl reversed phase column and isocratic elution with methanol: water (10/90, V/V). Detection was at 205 nm. Sub-part-per-billion concentrations were determined without precon-centration by injecting a 500 μL sample into the chromatograph. |
