  • Low-polar column with very low bleed and a wide application range
  • Suitable for drugs, solvent impurities, pesticides, hydrocarbons, PCB congeners (e.g., Aroclor mixes), essential oils, and semivolatiles
     

MXT®-20:

  • General-purpose, mid-polarity column for volatile compounds, flavor compounds, and alcoholic beverages
  • Low bleed
     

MXT®-35:

  • General-purpose, mid-polarity column for organochlorine pesticides, PCB congeners (e.g. Aroclor mixes), herbicides, pharmaceuticals, sterols, rosin acids, and phthalate esters
     

MXT®-50:

  • General-purpose mid-polarity column for pesticides, herbicides, rosin acids, phthalate esters, and sterols
     

MXT®-65:

  • General-purpose, mid- to high-polarity column for phenols, triglycerides, and fatty acids
     

MXT®-65TG:

  • High polarity phase specially tested for triglycerides
  • Should not be used for the analysis of compounds with active oxygen groups
     

MXT®-200:

  • General-purpose, mid-polarity column for solvents, Freon fluorocarbons, alcohols, ketones, silanes, and glycols
  • Excellent confirmation column with an Rtx-5 column, for phenols, nitrosamines, organochlorine pesticides, chlorinated hydrocarbons, and chlorophenoxy herbicides
     

MXT®-500 SimDist:

  • Non-polar column for simulated distillation
     

MXT®-502.2:

  • Application-specific column with unique selectivity for volatile organic pollutants
  • Cited in U.S. EPA Method 502.2 and in many gasoline range organics (GRO) methods for monitoring underground storage tanks
