SolEx Solid Phase Extraction Cartridges

Solid-Phase Extraction Defined

Solid phase extraction is defined as extraction of organic pollutants from a liquid sample using a solid phase adsorbent. The absorbent can be bound or encapsulated in a membrane filter (called disk format) or it can be packed in a cartridge (syringe bodies). The most common liquid sample extracted via solid phase is water (ground, waste and drinking). There are also many other applications such as the extraction of contaminants from milk, fruit juices, urine, etc.

Versatile Selection of Resins

The SolEx family of cartridges are offered in a variety of chemistries and sizes to fit your needs. The Summary tab shows a table of specs for each cartridge and disk along with some common applications.
