摘要

HIGH PURITY water is a vital resource for every scientific application, including those in acaclemia, and the pharmaceutical, cosmetic and food industries.Ultrapure reagent grade water can be defined as water that is void of material that can potentially interfere with laboratory methods, reagents or standards. Due to the high volumes of water used across numerous experimental methods, including those of sample preparation, liquid and gas chromatography, and mass spectrometry, extreme care must be taken to ensure an ultrapure water supply. This article reviews the significance of water purity in high performance liquid Chromatography (HPLC), oudines the origins of organic impurities in water, the technologies used to remove them and illustrates their effectiveness. System designs and configurations that eliminate interference are also discussed.
