PRS SPE Cartridge

Extracting weak bases in biological fluids


Finetech® PRS is a strong cation exchange sorbent with excellent retention for weakly basic compounds.

PRS shows unique selectivity owing to the absence of non-polar interactions. It is an alternative to SCX if non-polar components in samples couldn’t be removed by using the latter.

◆ Features:

  • High recoveries for pyridinic compounds

  • Simple retention mechanism, no non-polar interactions

◆ Specifications:


Carbon content: 4.5%

Surface area: 480 m²/g
Particle size: 40-75 μm
Pore size: 70 Å

◆ Applications:

  • Determination of drugs and their metabolites in biological fluids

  • Determination of basic pollutants such as malachite green,gentian violet, tetrodotoxin and methylene blue
