“…HPLC with UV/DAD (Bae, Kim, Jang, & Lee, ; Dasandi, Shivaprakash, Saroj, & Bhat, ; Liew, Loh, Tan, & Peh, ) had a sensitivity of about 50 ng/mL, but these methods needed a long chromatography run time (>12 min) and a large volume biological sample (>0.25 mL). High‐performance liquid chromatography–tandem mass spectrometry (HPLC‐MS/MS) was used in the determination of meloxicam (Ji, Lee, Kim, Jeong, & Lee, ; Lee, Ji, Kim, Lee, & Lee, ; Shirako et al, ). However its application was limited by the arduous and expensive sample preparation by solid‐phase extraction (Shirako et al, ) or time‐consuming and complicated sample preparation by liquid–liquid extraction (Ji et al, ; Lee et al, ), which could not meet the requirement for high throughput and speed in biosample analysis.…”
