Introduction to SPE Cartridges

SPE column or SPE cartridges are based on liquid-solid phase chromatography theory, it is a kind of extraction, separation, concentrated sample preparation unit. Mainly used in sample pretreatment of various foods, agricultural and livestock products, environmental samples and target compounds in biological samples.

Solid phase extraction fillers are usually chromatographic adsorbents. Hawach offers the following four categories.

The first one is based on silica gel (e.g. C18, C8, etc.); the second one is based on high polymers, such as polystyrene – Divinylbenzene and the like; the third type is mainly inorganic materials, such as Flory diatomaceous earth, alumina, graphitized carbon, etc.; the fourth type is a special column, such as an azo dye detection column.

Hawach SPE cartridges are made from medical PP and formed as injection syringe type, equipped with two pieces medical PE sieve plate, and chromatographic adsorbents (fillers) are filled between these two. The upper end of the SPE cartridge is open, and the lower end is a liquid outlet, and the liquid is discharged from the outlet after passing through the adsorbent. The conventional size of the column tube is 1 mL, 3 mL, 6 mL, and 12 mL.

In addition, Hawach can be customized according to your specific application requirements.
