Ultrapure Water Enables Excellent Chromatographic Performance for LC -MS Analysis

The need to ensure that standards, organic solvents and HPLC mobile phases are of the highest purity in LC/MS is widely recognised, yet water quality, which may have an impact on chromatographic performance and the quality of mass spectral data, is frequently taken for granted. In this application note TOC levels in PURELAB Ultra Analytic and PURELAB flex 3 are measured.
