Improved Recovery and Peak Shape

The Benefits of Glass Infusion™ Technology

The Zebron ZB-1XT SimDist metal columns employ a new proprietary bonding called Glass Infusion Technology. The Glass Infusion technology starts by depositing a very uniform layer of glass that completely covers the internal metal surfaces of the column. The result is a uniform coating throughout the column.

  • Uniform Glass Infusion ensures adequate covering of exposed metal to promote better recovery and peak shape.
  • Each Zebron ZB-1XT is individually tested to confirm and ensure excellent reproducibility.
  • The uniform glass coating provides a consistent foundation for stationary phase bonding, thus promoting better over-all efficiency and resolution.

  • Non-glass infused with exposed metal can cause tailing peaks and sample adsorption.
  • Some manufacturers batch test their columns, leading to poor column-to-column reproducibility.
  • These exposed surfaces result in abnormal bonding of the stationary phase which affects chromatographic performance, decreases efficiencies, and inconsistent performance between columns.

Better Results for High Temperature SimDist Analysis (ASTM D7169)

Why just settle with C90 or C100 when you can extend the performance to higher hydrocarbons and optimize productivity.  The combined ruggedness of the metal hardware and high temperature polymer used in each Zebron ZB-1XT SimDist column allows for extended analysis up to C120. With an extended analysis range, higher boiling point compounds will elute off the column instead of deteriorating column and system lifetime by remaining as residues.

Glass Infusion™ Technology provides improved efficiency, allowing sharper peaks and improved signal-to-noise for late eluting and low level components.
