Tamoxifen at a Cell Potential of 1000 mVThis example demonstrates that the EC oxidation products for a given compound oftencoincide with metabolites observed in biological assays. The Coulochem III Analyst driverallowed for automated analysis of tamoxifen using various EC cell potential. The simplicityand speed of on-line EC-LC-MS often provides an effective means of characterizing some ofthe many unknown metabolites encountered in multivariate profiling studies.54 Coulochem ® III Analyst Driver – Version 1.0User’s Manual
