Description

Analysis Note HILIC mode operation on an Ascentis Express column provided baseline resolution of these bath salts, including isobaric compounds. The highest quality LC-MS solvents were used to supply low background interference and low particulate contaminants for robust; trouble-free operation. Cerilliant CRMs provided reliable identification and quantification.
