- ... In the present study an ultra-performance convergence chromatography tandem mass spectrometry (UPC2-MS/MS) analytical method was developed and validated for the determination of 17 C19 and 14 C21 steroids, including C11-oxy C19 and C11-oxy C21 steroids. The limit of detection and limit of quantification ranged from 0.01 to 10 ng/mL and from 0.01 to 20 ng/mL, respectively, and the method shows the ...
