Reversed Phase C18 SPE Cartridges

Hawach Reversed Phase C18 SPE Cartridges have a high retention rate of the alkyl bonding phase for non-polar to moderate polar compounds. The hydrophobic reverse phase filler can retain most of the non-polar compounds and most of the organic analytes in the aqueous matrix.

C18 (end-capped) is a reversed-phase C18 SPE cartridge based on silica gel. It has the characteristics of high bonding density, low loss, and high recovery rate. C18 solid phase extraction cartridge is mainly used in the desalination of macromolecular samples such as drugs and their metabolites, proteins, and DNA in blood, plasma, and urine, and the enrichment of organic matter in environmental water samples.

The C18 (end-capped) solid phase extraction column uses octadecyl silica gel as the packing to retain non-polar compounds through strong hydrophobic interaction. The filler can retain most organic matter and is widely used in the environment, food safety, and other fields.
