CarboPrep material is available in two different published surface areas: CarboPrep 90 adsorbent, which has an approximately 90 m2/g surface area, and CarboPrep 200 adsorbent, which has approximately 200 m2/g surface area. These are both considered general-purpose products. In contrast, CarboPrep Plus cartridges use a carbon adsorbent with a proprietary surface area that has been specifically optimized for the cleanup of organochlorine pesticide extracts.
