Advanced Graphene Products has recently introduced a new line of products – High purity graphene oxide water solutions.
Manganese content 0.0006 %.
Careful washing process provides high purity of graphene oxide dispersion. Manganese amount was measured using electron paramagnetic resonance to verify the high purity of the material.
Contamination by manganese is, due to the production process, the often defect of commercially available graphene oxide. Thanks to high purity, our product does not show toxicity in living cells.
