Quality control

All our samples are subjected to a rigorous QC in order to ensure a high quality and reproducibility of the graphene. All our CVD materials are processed in ISO 7 Cleanroom. Each batch must pass the following tests:

• · Raman Spectroscopy on each batch:  I(G)/I(2D)<1; I(D)/I(G)<0.1 on 90nm SiO2/Si substrate.

• · Optical Microscopy inspection of each individual sample to ensure good transfer quality and purity

If your application requires more specific controls (AFM, SEM...) please do not hesitate to contact us.
