Bond Elut Carbon/PSA, 500/500 mg, 6 mL, 30/pk. Bond Elut Carbon, Bond Elut Carbon/NH2, and Bond Elut Carbon/PSA cartridges are optimized for the absorption of pigments in food, fruits and vegetables, and small organic wastewater residues. Ultrapure graphitized carbon particles enable powerful retention mechanisms for a broad range of analytes. Careful manufacturing techniques result in lower carbon fines on the device wall.;Carbon/NH2 and Carbon/PSA contain NH2 and PSA, respectively, for enhanced removal of polar compounds.
