Description
Analysis Note
The extremely rapid (~3 minutes) resolution of six antifungal compounds on an Titan C18 column is shown in this application. Titan particles feature totally porous, monodisperse silica. The highest grade 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.
