Desiccants can absorb water and bind it chemically (reversibly or irreversibly) or physically. The main desiccants can be subdivided into four categories:
- non-renewable chemical desiccants
- renewable chemical desiccants
- silica gels
- molecular sieves

Ultra Pure Metals and Inorganic Compounds
The ROTI®METIC product range comprises more than 130 high purity inorganic metals and metal compounds with purity levels ranging from 99,9 % (3N) to 99,9999 % (6N). Modern production technology as well as high quality and safety standards make it possible to achieve these high purity levels of metal traces from 100 ppm to 1 ppm. Up to 60 trace metal compounds are analysed by HR-ICP, ICP-OES, AA, GD-MS and documented in the batch specific certificate of analysis supplied with the product. Our ultra high purity metals and metal compounds are ideal for the following applications:
- Instrumental analytics
- Chemical analyses & syntheses
- Crystal growth technology
- Laser and Photovoltaic technology
- Optical fibres
- Fuel cells
|Assay (metals basis)||99,995 %|
|Chemical analysis (ICP, AAS): up to 60 specified trace metal impurities in ppm range.|
