Presentation
The new process developed by the LMOPS laboratory of the University of Lorraine enables the measurement of salt concentration in a product containing at least a portion of water, with a Raman spectrometer. This technique does not require to sample or touch the product, whatever the product external conditions.
Different salts can be measured : chlorides, nitrates, sulfates, phosphates, acetates, formates, urea,…, or a combination of them.
Competitive advantages
- Rapid (a few s), non contact measurements are possible;
- Low analytical costs (simultaneous measurement of different salts);
- Low maintenance costs;
- Insensitivity to suspended matter;
- Possibility to perform long range measurements on several samples in a row;
- Precision: of the order of a mg/L.
Applications/Markets
- Fabrication de préformes ou de pièces prêtes à être brasées;
- Brasage de tuyauterie simplifiée et qualité assurée;
- Assemblage de pièces en cuivre.
Intellectual property
- Patent FR2937421;
- Collaboration sought: license for device manufacturing and distribution.
