MonoTrap is a new material for easy trapping of compounds and extracting by solvent or temperature. The big surface and strong chemical adsorption with Graphite Carbon, ODS or PDMS makes it a very easy and cheap consumable.

• Highly Efficient Adsorption
  MonoTrap’s high surface area offers greater sample loading capacity, ensuring a higher concentration of adsorbed compounds


• Complete Desorption with low Solvent Volume
  It only takes a small amount of solvent, 200 µL, to completely saturate the monolithic network and achieve desorption, though more solvent can be used to control the final concentration of your sample.


• Hydrophobic Surface
  using hydrophobic ODS groups, MonoTrap will not adsorb water from aqueous samples. No need to worry about injecting water onto your GC or GC/MS when using MonoTrap as with liquid-liquid extraction or other sorptive media. This also allows for the addition of ionic salts to improve sample adsorption with MonoTrap.


• Multiple Injections & Analyses
  Because compounds adsorbed to MonoTrap can be extracted using 200 µL (or more) of organic solvent, it is no problem to perform multiple injections of your sample. With MonoTrap, it is even possible to make injections on different GC systems utilizing different column phases! Solvent extraction can even be accomplished within a GC autosampler vial using the rod shaped MonoTrap.


• Ideal for off line sampling
  MonoTrap comes ready to use straight from the package. Also the sampling traps are not expensive and can be used as disposable, this combination makes MonoTrap ideal for off line sampling.
