Using sophisticated computer modeling software, Restek created two stationary phases for separating the 53 organophosphorus pesticides (OPP) listed in EPA Method 8141. The extended upper temperature limit of these phases (330°C) allows analysts to bake out high molecular weight contamination typically associated with pesticide samples. The low-bleed columns are a perfect match for sensitive detection systems.
  • Proprietary Crossbond phases
  • Fused silica
  • Low bleed makes it ideal for GC-FPD, GC-NPD, or GC-MS analyses
  • Improved separation and reduced analysis time
  • Stable to 330° to 340°C
