说明
分析说明
The apHera C18 HPLC column packed with polymeric particles demonstrated excellent peak shape and rapid elution for these bulky, immunosuppressant compounds under conditions not permitted by silica-based HPLC columns. 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.
