Description

Analysis Note The simple extraction from plasma and rapid separation of the street drug Flakka (α-PVP) and a related compound is shown here on an Ascentis Express HILIC column in HILIC mode. Highest grade UHPLC solvents were used to supply low background interference and low particulate contaminants for robust, trouble-free operation. Cerilliant CRMs provided reliable identification and quantification.
