Carbon coatings - Import export

Limit values (so called MAK-value) for pollutants in ambient air have been defined by law, which should not be exceeded. This is done with the help of specially coated activated carbon that is amongst others in the activated carbon filter, and removes pollutants from the air of the wearer. But from the first, the breathing air needs to contain at least 19% oxygen! Dependent on application area you can choose between filter types as follows: Type A: colour code: brown Organic vapour or gas with boiling point above 65°C Type AX: colour code: brown Organic vapour or gas with boiling point under 65°C Type B: colour code: grey Inorganic vapour or gas (no CO) Type E: colour code: yellow Sulphur dioxide and acid gases or vapour Type K: colour code: green Ammonia and ammonia derivates Type Hg: colour code: red Mercury vapour Type CO: colour code: black Carbon monoxide Type P: colour code: white Dust Breathing filters, depending on filter type, can remove certain pollutants from...

NKCG produces graphite tube technology (GF-AAS) for medical analysis. The target of the process is to determine the elements and obtain optimal results in medical analysis. These tubes and cuvettes are coated by CVD pyrolytic carbon coating (NK-PyC) and furthermore purified (NK-PURE).
