Poroshell HPH

Poroshell HPH Guard Columns from Agilent Technologies

High-performance Agilent UHPLC guards are designed for use with fast LC columns. They connect directly to the column inlet; no extra hardware is needed.

Agilent UHPLC guards are available in all InfinityLab Poroshell 120 chemistries—giving you confidence that the guard column will not adversely affect your separations.

InfinityLab Poroshell HPH-C18 and HPH-C8 particles are made by chemically modifying the porous layer using proprietary technology that provides high-pH stability.

Three particle diameters— 1.9 µm, 2.7 µm and 4 µm —allow you to choose the size that best fits your separation needs, and is most compatible with your LC systems and 12 different chemistries provide a range of selectivities that makes your method development fast and easy.
