Copure® HLB SPE Cartridges

Extracting apolar to moderately polar acidic, neutral and basic compounds
Details

Copure® HLB sorbent is composed of monodisperse N-vinylpyrrolidone-divinylbenzene copolymer resin particles, with specific mixture of hydrophilic hydrophobic groups, allowing for retention for a wide range of compounds with very high capacity.

HLB can be used as a general-purpose sorbent, especially for extracting analytes from complicated samples such as blood and urine.


Features:

  • General sorbent, suitable for wide application areas
  • Highly wettable, no worry of bed dryness, rare breakthrough
  • Highly recoveries, excellent reproducibility
  • 3 to 10 times higher adsorption capacity and loadability than C18-bounded silica gel
  • Stable from pH 1 to 14, compatible with common solvents

Specifications:

Surface area: 600 m2/g
Particle size: 40 μm
Pore size: 300 Å

Applications:

  • Determination of drugs, illicit drugs and their metabolites in blood, such as sertraline ibuprofen and heroin
  • Determination of residual antibiotics, catecholamines, and microcystins in foodstuff
  • Determination of veterinary drugs, pesticides and mycotoxin in milk products
