CHROMABOND^® HR-X, a spherical hydrophobic polystyrene-divinylbenzene adsorbent resin.

• state-of-the-art spherical polymer
  broad spectrum of application with special suitability for
  enrichment of pharmaceuticals from biological matrices
  ideal flow properties due to low content of particulate matter
  
  
• optimised pore structure and high specific surface
  high loadability and outstanding elution properties
  low solvent consumption
  rapid, economical analyses
  
  
• high-purity adsorbent
  allows highest reproducibility with extremely
  low blind values
  reliable analyses at ultra trace level
  no method adaptation for new batches necessary

• hydrophobic polystyrene-divinylbenzene copolymer, pH stability 1-14
  
  
• high-purity material with highest reproducibility and lowest blind values due to a novel manufacturing process
  
  
• spherical particles 85 µm; pore size 55-60 Å, very high surface 1000 m²/g,
  capacity 390 mg/g (caffeine in water)
  
  
• excellent recovery rates especially for the enrichment of pharmaceuticals/active ingredients due to the spherical structure of the particles, very homogeneous surface, and optimised pore structure
  
  
• recommended applications:
  pharmaceuticals/active ingredients from tablets, creams and water/waste water
  drugs and pharmaceuticals from urine, blood, serum and plasma
  trace analysis of pesticides, herbicides, phenols, PAH and PCB from water
