Welchrom GraphiCarb

Activated carbon adsorption capacity is large, but the adsorption is irreversible and the extraction is difficult to elute. Welchrom® GraphiCarb overcomes the shortcomings of irreversibility of activated carbon adsorption while remaining high affinity for both polar and non-polar organic substances and large adsorption capacity. Therefore, it has excellent properties such as high purification effect, high recovery rate and high reproducibility, which is widely used in agricultural residue analysis and sample pretreatment with high pigment content. In addition, graphitized carbon is not porous material, so it takes a short time to reach adsorption equilibrium, which means it can save the time of sample treatment.
