BPX - High performance/High temp

Features to look for when Purchasing a Column

  • Low bleed
  • Maximum temperatures
  • Column inertness
  • Resistance to chemical degradation, air and water
  • Produces needed results

SGE Stationary Phases

  • BP - Conventional technology
  • BPX - High performance / high temperature
  • HT - Very high temperature Capillary Columns

Features of BPX Columns:

  • BPX has the highest temperature rating on the market
  • Dramatically increases the range of analysis
  • Longer column lifetimes
  • BETTER PERFORMANCE ms grade column for routine applications higher operating temperatures column inertness
  • LONGER COLUMN LIFE lower bleed greater column inertness resistance to oxidation by air
  • LOW COLUMN BLEED
  • EXTENDED TEMPERATURE
  • RESISTANT TO AIR OXIDATION
  • CHROMATOGRAPHIC INERTNESS

BPX Chromatograms

Basic Rules of Column Selection

  • Know your components
  • Use the least amount of theoretical plates as possible (uses less time)
  • Know your phases: maximum temps, polarities
  • Know your basic rules of chromatography
  • If you have one in your cupboard - try it!
  • Look at the literature
  • Ask SGE
  • If in doubt, use a: 30 M x 0.25 mm ID 0.25 micron BPX5
