Screening method for NSAIDs (Hon-Steroidal Anti-Inflammatory Drugs) in urine was developed using GC/NCI-MS. Derivatized six fenamates with pentafluoropropionic anhydride showed high sensitivity in NCI-MS. The conditions of the derivatization reaction and chromatographic conditions were established for screening with a trace analysis. Limit of detection was in the range of 4-25 pg/mL. This method may be used to the equine doping analysis for NSAIDs and forensic analysis.
