What is the difference in USP Charcoals?
Both USP grades of AC Powder we sell on site have the same particle surface area. Total surface area is not dependent on how fine the powder is. Pound for pound they have the same surface area. There are over 150 grades of Activated Charcoals, each designed to target different applications. That depends a good bit on the size of the molecules/particles that are to be adsorbed. The surface area and pore structure of the individual charcoals are matched to the particles to be removed from whatever. Some charcoals have a broad range of internal structures to accommodate a broad range of chemicals/particles, others are very specific. We have listed these two USP grade charcoals for internal use, but USP grades are certified so that they can also be used in other medical applications including dialysis units, wound dressings, hemoperfusion cartridges. As well, the Pharmaceutical industry must use USP certified charcoals for “cleaning” drugs of unwanted odors, flavors, colors. For internal a

We have listed these two USP grade charcoals for internal use, but USP grades are certified to meet standards set for the Pharmaceutical industry. The Pharmaceutical industry uses USP certified charcoals for “cleaning” drugs of unwanted odors, flavors, colors. For internal application it really becomes a matter of preference. The acid-washed USP grade has a ve
