UHPLC Guard Column Poroshell 120 PFP, 4 µm, 2.1 mm, 3 pc/pak

Poroshell 120 PFP UHPLC guard column with inner diameter 2.1 mm, length 5 mm and particle size 4.0 µm. 3 pieces per pack. Poroshell 120 PFP columns offer alternative selectivities and superior peak shapes for polar and non-polar analytes and are ideal for aromatic and halogenated compounds for improved chromatography.

PFP is a pentafluorophenyl ligand that provides an orthogonal separation mechanism with C18 chemistries. PFP phases can separate analytes based on small differences in structure, substitution, and steric access to polar moieties. The resulting selectivity for positional isomers, halogenated compounds and polar analytes is particularly useful in the analysis of complex mixtures.
