Frequently Asked Questions
- Is Resteks Ultra-Clean resin really the same as XAD-2 resin? Yes. Resteks resin has been manufactured to match the original XAD-2 specifications of composition, pore size, and surface area. You will experience identical sampling performance for all semivolatile compounds.
- Does Resteks Ultra-Clean resin need to be baked-out prior to use? No. Resteks resin is precleaned and prebaked. Unlike other resins, Resteks resin is rigorously cleaned and baked prior to being bottled. When we say our Ultra-Clean resin is precleaned, you can count on it!
Although resin is an excellent adsorbent for trapping PAHs, it requires extensive cleanup because many of its impurities are PAH compounds. To enable you to eliminate time-consuming cleanup, we do the cleaning for you! We test each batch by capillary GC–flame ionization detector (FID) to ensure cleanliness. However, depending on your application, additional cleaning may be required.
