Introducing ZB-5MS PLUS
The Next Generation of Inertness


  • Improved Responses
  • Better Peak Shapes
  • Same 5ms Selectivity
Low bleed 5% phenyl-arylene phase maintains the same selectivity you're used to.
Ultra inert deactivation dramatically reduces analyte adsorption,maximizing your detection power.

Change Your Column

Not Your Method

Drop a ZB-5MSPLUS into Your Current GC Method with Ease

Achieve better performance over your current 5% phenyl-arylene column without changing your method. Zebron ZB-5MSPLUS GC columns provide tremendous inertness while achieving higher responses and superior peak shapes for active compounds. Whether you’re analyzing drugs of abuse, melamine in food, or specialty chemicals expect better peak shapes with no shifts in retention times when you drop in a Zebron ZB-5MSPLUS into your current method.
