Opis
Komentarz do analizy
HybridSPE-Phospholipid plates removed plasma-derived proteins and phospholipids to maximize LC/MS sensitivity. Titan C18 U/HPLC columns provided rapid resolution. 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.
