application for HPLC

Właściwości

• metody: HPLC: suitable
• parametry testowe: sample/matrix: urine samples spiked at 100 ng/mL with each target analyte (To ensure full ionization of the analytes, spiked samples were treated with formic acid to a final concentration of 0.1% formic acid.); SPE tube/cartridge: Supel-Select SCX, 30 mg/1 mL (54240-U); condition: 1 mL 1% formic acid acetonitrile then 1 mL water; sample addition: 1 mL spiked water blank or urine; washing: 1 mL water, 1 mL 1% formic acid acetonitrile, 1 mL water; elution: 2 mL 10% ammonium hydroxide in acetonitrile; eluate post-treatment: thoroughly mix via vortex agitation, evaporate 1 mL aliquot to dryness, reconstitute in 100 μL water:methanol; column: Ascentis Express HILIC, 10 cm x 2.1 mm I.D., 2.7 μm particles (53939-U); mobile phase: (A) 5 mM ammonium formate acetonitrile; (B) 5 mM ammonium formate water; (98:2, A:B); premixed; flow rate: 0.6 mL/min; pressure: 1842 psi (127 bar); column temp.: 35 °C; detector: MS, ESI(+), TIC, m/z 100-1000; injection: 1 μL; sample: 200 μg/L ea. in acetonitrile

Opis

Komentarz do analizy

Bath salts are psychoactive designer drugs of the phenethylamine and cathinone families. Shown here is the rapid, sensitive LC/TOF-MS analysis of nine bath salts extracted from human urine using polymeric SPE on Supel-Select SCX and separated on an Ascentis Express HILIC column. Notice the lack of interfering peaks in the chromatogram demonstrating the effectiveness of the sample cleanup. Cerilliant CRMs were used to ensure reliable MS identification and quantification.
