Excellent chromatographic performance using ultrapure water in LC-MS analysis
2021-04-04 08:02:15
Liquid chromatography-mass spectrometry (LC-MS) is a powerful and effective analytical method that combines the separation capabilities of high performance liquid chromatography (HPLC) or ultra high performance liquid chromatography (UHPLC) with the mass spectrometry capabilities of mass spectrometry. It is well known that in order to ensure a high standard of analysis, it is necessary to use an organic solvent having the highest purity and an HPLC mobile phase having the highest purity. Therefore, it is natural to use high quality water because the quality of the water has a significant impact on the results of the chromatographic analysis and the quality of the mass spectrometry data.
