Description of PRS SPE Cartridge

The PRS propane sulfonic acid strong cationic SPE cartridge is a strong cation exchange type extraction cartridge with propane sulfonic acid bonded silica as a filler, which has good retention ability for weakly basic compounds.
There is no non-polar secondary action in the PRS and thus has a unique selectivity. When using SCX SPE cartridges, when non-polar components in the sample matrix interfere, PRS can be used for extraction.

Characteristics of PRS SPE Cartridge

  • The high recovery rate for pyridines;
  • Single separation mechanism, no secondary interaction.


  • Carbon content: 4.5%;
  • Specific surface area: 310 m²/g;
  • Particle size: 40-75 μm;
  • Average pore size: 100 Å.

Application of PRS SPE Cartridge

  • Detection of pyridines and their metabolites in biological matrices;
  • Determination of alkaline pollutants such as malachite green, crystal violet, tetrodotoxin, and methylene blue

Relevant Standards

  • Determination of malachite green in feed for NY/T 1756-2012.
  • GB 20361-2006 Determination of malachite green and crystal violet residues in aquatic products – high-performance liquid chromatography.
