Method Performance Evaluation

Calibration standards and QC samples were prepared in artificial urine.

Concentration of the highest calibration standard was limited by concentration of

individual analytes stock solutions (1 mg/mL) purchased from Cerillant.

The following method performance parameters were obtained:

LOQ:

precision within 20% and ion ratio within specified range

Linearity range

: all calibrators accuracy 15%

Precision:

5 replicates of QC samples

Matrix effects

: Internal standard peak area %Recovery in donor samples (n=40)

calculated against internal standard peak area in water.

Deuterated internal standards for each analyte (not listed at the graph) were

analyzed with the same analyte specific time windows.
