CHROMABOND^® HR-XCW – SPE Cartridges

Weak Carboxylic Acid-Modified Polymeric Cation Exchanger for SPE

This innovative SPE phase is a state-of-the-art spherical polymer and is appropriate for a broad spectrum of applications. HR-X is especially suitable for the enrichment of pharmaceuticals from biological matrices and has ideal flow properties due to its low content of particulate matter.

Its optimized pore structure and high specific surface allow for high loadability and outstanding elution properties, low solvent consumption, and rapid economical analyses. High-purity adsorber material allows the highest reproducibility with extremely low blind values and reliable analyses at ultra-trace levels. Method adaptation for new batches is not necessary.

Properties:

Base material spherical PS/DVB copolymer, pore size 50-60 Å, particle sizes 45 µm or 85 µm (standard)
Very large specific surface 850 m²/g, pore volume 1.2-1.4 cm³/g, pH stability 1-14
Weak carboxylic acid modification, exchange capacity > 0.7 meq/g, pKa ~ 5
RP capacity 350 mg/g (caffeine in water)
High-purity material, highest reproducibility and lowest blank values due to an optimized production process
Outstanding recovery rates especially for the enrichment of basic analytes

Recommended Applications:

Basic compounds like quaternary amines
Basic active ingredients from strongly matrix-contaminated samples like urine, plasma, serum
Strong bases with pKa > 10
