SHINWA Normal Phase HPLC Columns


Normal Phase Chromatography HPLC Packed and Guard Columns

  • ULTRON VX-SIL columns use high purity silica gel (SiO2 99.99% or higher), thereby reducing sample absorption by metal oxides to the lowest possible levels. Taking into consideration analytical pressures and column lifetimes, spherical silica particles are used in these columns. Correspond to USP number L03: Porous silica microparticles, 5 to 10 micrometers in diameter.
  • ULTRON VX-SIL guard columns are packed with the same types of silica gels that are used in analytical columns. Appropriate use of guard columns results in good reproducibility and long operating lifetimes.
