Ash content and graphitization degree typically require third-party laboratory testing (XRD, TGA). We can coordinate this for you.
For rod-shaped materials, we can perform electrical resistance and resistivity measurements in house, which is faster and more cost-effective.
We recommend selecting tests based on your actual needs. For process validation, weight change and resistivity may suffice; for formal reporting, full characterization may be required.
Tell us which metrics you need and we'll plan the testing protocol.
