Introduction of SPE Column From Hawach


In terms of the filler type, SPE column can be divided into four applications of silicone bonding matrix, polymer matrix, absorption matrix and specialized columns. Besides, the silicone bonding has four sorts—antiphase(C18 sealing end/uncapped/hydrophile, C8), positive phase(Silica,Diol, CN), ion exchange(SAX, SCX, NH2, PRS, PSA) and mixed mode(C8/SCX, C8/SAX). Similarly, according to HLB(Hydrophile-Lipophile Balance), the polymer one possesses series of MCX, MAX, WCX and WAX.

Alumina, graphitized carbon black and Florisil pesticide residues are involved into the absorption matrix.

Essential Parameters


Any part of the material directing touched by terminal customers would contaminate their samples, so there are instructions set on every material section.

Parameters of Stationary Phase

matrix type (e.g. silica gel or polymer)

bonded phase type (e.g. C18 or CN)

particle size (e.g. 3or 5 um)

surface area of stationary phase (e.g. 130 m2/g)

bore diameter


purity of stationary phase

Column Specification

It means the volume or the filling content, which decides the Sample throughput.

Naming Rule

It consists of item number, specification and package(pcs/pk).
For instance, SLSPE1001SI stand for SPE column from Hawach with 100 mg and made of Silica.
