- Metchem Laboratories use the wet chemical method to determine the percentage chrome and Iron in samples.
- A specific mass of a homogeneous sample is fluxed with chemicals and fused with an auto fluxer.
- The fused portion is treated with chemicals and titrated with Ferrous Ammonium Sulphate. Known certified standards are analysed with every batch of samples to ensure trustworthy results.
- We also analyse other elements in samples eg SiO2, MgO, MnO, V2O5, P, TiO2, MgO, CaO etc. These are done by fusing a specific mass of sample and treating the fused samples with chemicals after which the samples are read on the ICP.
