Airborne Molecular Contamination
The term Airborne Molecular Contamination (AMC) describes solid or liquid particles with a diameter of up to 100 nanometers as suspended matter in the air in a clean room .
These particles cause undesirable chemical or physical changes on surfaces, in particular on the surfaces of the test objects (during research) or the workpieces (during production).
Such small particles are more difficult to detect and more difficult to filter (compared to larger particles).
It has been surprisingly known since 2018 that acetic acid and formic acid play the most important roles in this area. ( Science , Vol 361, Iss 6404)
