Name: SIELC HPLC Guard Column Primesep B4 2.1x10mm 5 μm 100 Å
Brand: SIELC

Primesep B4 is a reverse-phase (short carbon chain) analytical column with embedded basic ion-pairing groups. Improves retention of acidic compounds by anion-exchange mechanism. Retains and separates basic and acidic surfactants based on multi-mode mechanism. Separates hydrophobic bases by ion-exclusion mechanism. Retains hydrophobic neutral compounds by reverse-phase mechanism. All mobile phases are LC-MS and preparative chromatography compatible (working pH range from 2.0 to 4.5).Mostra di più
