Rapid Analysis of 17 Bile Acids in Human Plasma by LC-MS/MS
17 Jan 2019Quantitative analysis of bile acids in plasma is critical for diagnosing liver disease as well as assessing drug safety. Accurate reporting can be difficult because of analyte characteristics, matrix effects, and other factors. Here, we establish a rapid, robust, and selective LC-MS/MS method for the analysis of bile acids in human plasma using a Restek Raptor C18 column. One of the significant improvements over other reported methods was the baseline separation of all 17 bile acids in 6 minutes, including three isomer groups.

Raptor™ C18 LC Columns (USP L1)
Restek Corp.Restek chemists became the first to combine the speed of superficially porous particles (also known as SPP or “core-shell” particles) with the resolution of highly selective USLC® technology. This new breed of chromatographic column allows you to more easily achieve peak separation and faster analysis times without expensive UHPLC instrumentation.
