HPLC columns made in Japan

Inertsil C8-3 Columns
  • Virtually perfect peak shape for most bases and acids
  • Unique selectivity
  • Exceptional physical and chemical durability provides long column life
  • Vast database of chromatographic applications available to assist in method development
  • Very low operating back pressure

Inertsil C8-3 provides pure reverse phase characteristics that are critical to resolving highly polar compounds like acidic and basic pharmaceuticals. The near perfect C8 ( octyl ) phase and end-capping coverage on this material results in symmetric, narrow peaks for even the most polar compounds while using simple eluents like aqueous MeCN or MeOH. The need for ion-pair and competing-amine eluent modifiers that are necessary with many other reverse phase columns is eliminated on Inertsil 3-series phases. The Inertsil 3-series represents a major advance in performance over the original Inertsil 2-Series. Inertsil 3-Series phases, including ODS-3, ODS-3V, ODS-SPRINT, ODS-P, ODS-EP, Ph-3, CN-3,NH2, Diol and SIL-100Å, are based on a purer, higher surface area silica which is specially manufactured to provide maximum bonded phase coverage. The result is a series of columns which provide excellent peak shapes using simple eluents while operating at low pressure.
