Scientists from the Lunan Pharmaceutical Group explored the use of UHPLC-MS/MS to test the effects of Shouhui Tongbian capsules (SHTBs) on slow transit constipation (STC).
Turbulent-Flow LC for LC–MS and LC–MS–MS Bioanalysis
This month's "Directions in Discovery" gives a brief overview of turbulent- flow liquid chromatography, a technique for fast separations. Two examples demonstrate the use of the technology for high-throughput bioanalytical separations in drug discovery.
A Comparison of CE–MS and LC–MS for Peptide Samples
January 1st 2000Despite their different levels of technological maturity, CE and LC coupled with electrospray ionization MS techniques can be operated at the same level of automation. However, they differ in their configuration, selectivity, sensitivity, and method development.
