Technical details of ultra-inert solid-core columns with extended pH stability

ACE UltraCore Technical Information:

  • Ultra-inert solid-core particles
    • 2.5μm and 5μm ultra pure solid-core (superficially porous) particles
    • Monodisperse particle distribution combines high efficiency with low pressure
    • Achieve UHPLC efficiency and performance on HPLC instrumentation
  • SuperC18 and SuperPhenylHexyl phases
    • Two bonded phases give complementary selectivity for rapid, systematic method development
    • Excellent reproducibility and column lifetime
    • Ultra-inert phases ensure excellent peak shape
  • Extended pH stability
    • Exploit selectivity changes at low, intermediate and high pH
    • Designed for use with LC/MS compatible buffers
    • Recommended pH range 1.5 - 11.0
