Description
PRS SPE Cartridge: High-Selectivity Sorbent for Strong Cation Exchange
The PRS (propane sulfonic acid) solid-phase extraction (SPE) cartridge is a strong cation exchange sorbent designed for efficient retention of weakly basic compounds. It utilizes propane sulfonic acid bonded silica as a filler, offering a highly selective extraction mechanism with minimal secondary interactions.
Unlike SCX SPE cartridges, which may retain non-polar components from the sample matrix, PRS provides a cleaner separation with no non-polar secondary interactions. This makes it an ideal alternative when SCX sorbents lead to matrix interference.
Key Features
- High recovery rate for pyridines and other weakly basic compounds
- Single separation mechanism with no secondary hydrophobic interactions
- Reduces matrix interferences that may occur with SCX sorbents
Applications
- Pharmaceutical and clinical analysis
- Detection of pyridines and their metabolites in biological matrices
- Environmental and food safety testing
- Determination of alkaline pollutants such as malachite green, crystal violet, tetrodotoxin, and methylene blue
The PRS SPE cartridge provides highly selective retention for weakly basic analytes, making it an excellent choice for biomedical, environmental, and food safety applications where minimal matrix interference is required.
