Descrizione

Risultati analitici

An Ascentis Expres F5 column provided rapid, baseline resolution of testosterone and metabolites. 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.
