LC/MS Analysis of Amphetamine Enantiomers on Astec CHIROBIOTIC® V2

LC/MS Analysis of Amphetamine Enantiomers on Astec CHIROBIOTIC® V2


column Astec CHIROBIOTIC V2, 15 cm x 4.6 mm I.D., 5 µm particles (15023AST)
column temp. 20 C
mobile phase [A] methanol; [B] water; [C] acetic acid; [D] ammonium hydroxide; (95:5:0.1:0.02, A:B:C:D
flow rate 1 ml/min
pressure 1220 psi (84 bar)

Analysis Note Astec CHIROBIOTIC columns are unique in their ability to operate in MS-friendly mobile phases, and with polar analytes. Demonstrated here is CHIROBIOTIC V2 for the resolution of the enantiomers of amphetamine. High purity solvents provided robust operation, and Cerilliant CRMs provided reliable quantification.
