UHPLC Guard Column Poroshell 120 HPH-C18, 1.9 µm, 3 x 30 mm, 3 pc/pak

InfinityLab Poroshell HPH-C18 UHPLC guard column with inner diameter 3 mm, length 30 mm and particle size 1.9 µm. 3 pieces per pack.

Poroshell 120 HPH columns have high pH stability (pH 2.0-11.0). They are characterized by the resolution of basic compounds (pKa > 6) with sharp peaks and are ideal for complex samples and various mobile phases.

The hybrid particle technology in HPH-C18 columns improves the overall stability of the particles at high pH values and enables longer lifetimes and fewer column changes. The selectivity of HPH chemistries is very similar to EC-C18 and EC-C8, allowing for easy method transfer.
