WebIn this report, we developed a sensitive and accurate LCMS method for the determination of BPA in urine after derivatization with 1-methylimidazole-2-sulfonyl (IS) chloride in a simple and quantitative reaction. The resulting BPA-IS adduct showed a LOD of 0.12 pg/mL by tSIM and was 9 times more sensitive than the BPA-dansyl derivative.

Web1 apr. 2024 · One of the three main technologies used to perform metabolomic analyses is Liquid-Chromatography Mass Spectrometry (LC-MS). Data analysis for this technology requires a large variety of steps, ranging from extracting information from the raw data to statistical analysis and annotation. WebAn adduct (from the Latin adductus, "drawn toward" alternatively, a contraction of "addition product") is a product of a direct addition of two or more distinct molecules, resulting in a … link ea account with ps5
