WebAbstract. The use of boronate affinity chromatography for separation of nucleic acid components and carbohydrates was first reported by Weith and colleagues in 1970 (1). Since then, the specificity of boronate has been exploited for the separation of a wide variety of cis-diol-containing compounds, including catechols, nucleosides, nucleotides ... WebTo this end, herein, a method was developed for the determination of seven MAH metabolites through ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). An aliquot of 0.5 mL urine was fortified with an isotopic labeled internal standard solution before being hydrolyzed by 40 μL of 6 mol/L HCl solution, followed by ...
