Trace Contamination Detection
Sometimes products can become contaminated during the production process. Contamination can occur in a wide range of products, including chemicals, flexible electronics, cosmetics, food packaging, pharmaceuticals, and petroleum products. Chemical testing identifies the presence of specific contaminants, and the manufacturer can then use this information to identify and rectify the causes of contamination.
Trace contamination may be in the form of particles, cloudiness, surface residue, or trace chemicals left over from the manufacturing process.
For example, the tanning process for leather often uses chromium, but finished leather products must be free of any traces of chromium in order to comply with the EU's REACH regulations. If chromium is detected in leather samples, it could indicate that the tanning process was not done properly.
