Description

Analysis Note

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