CHROMABOND^® HR-XC, strong mixed-mode polymer-based cation exchanger for basic analytes

• mixed-mode SPE phase with distinct cation exchange and RP properties
  excellent enrichment of basic analytes
  
  
• modern, spherical support polymer
  with optimised pore structure and large surface
  good reproducibility, reliable and cost-efficient analyses
  
  
• more aggressive washing procedures for matrix removal possible
  cleaner samples and protection of your HPLC and GC instrumentation
  
  
• quantification of analytes from heavily contaminated samples
  lower limits of detection also for critical matrices

• strong benzenesulphonic acid cation exchanger exchange capacity 1.0 meq/g
  
  
• base material polystyrene-divinylbenzene copolymer pH stability 1-14
  RP capacity 300 mg/g (caffeine in water)
  
  
• high-purity material, highest reproducibility and lowest blank values due to an optimised production process
  
  
• spherical particles, particle size 85 µm; pore size 65-75 Å
  very large specific surface 800 m²/g; pore volume 1.4 cm³/g
  
  
• outstanding recovery rates especially for the enrichment of basic analytes
  
  
• recommended application:
  basic active ingredients from strongly matrix-contaminated samples like e.g. urine, plasma, serum
  fungicides from food
  basic analytes like e.g. amines
