HPLC Guard Column PL Hi-Plex H, 8 µm, 7.7 × 50 mm

Hi-Plex HPLC columns provide reliable carbohydrate analysis with simple instrumentation. Unlike ion chromatography columns, Hi-Plex columns are used with pure water or dilute acid on a standard HPLC and do not require ion regeneration or suppressors.

The media consists of a robust, sulfonated, cross-linked styrene-divinylbenzene gel in hydrogen form or impregnated with various metal cations with different selectivities as described in USP L17, L19, L34 and L58. Hi-Plex HPLC columns are available in 8 μm and 10 μm particle sizes. This guard column has the inner diameter 7.7 mm, the length 50 mm and the particle size 8.0 µm.
