Description of PRS SPE Cartridges

Starlab Scientific Co., Ltd’s PRS is a silica gel based strong cation exchange column. It’s consisting of a propane sulfonic acid, has slightly less exchange capability than SCX SPE cartridge. It is suitable for weak cation such as pyridine compounds, can get high recovery rate. Typical applications include malachite green and crystal violet in water or in biological samples and other alkaline substances.
