Description
Analysis Note
Shown here is a method to rapidly screen a sample for a variety of abused substances using an Ascentis Expres F5 column. 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.
