DETERMINATION OF THE SALT CONCENTRATION OF AN AQUEOUS SOLUTION
A method of determining the concentration of a salt that may be present in a substance containing at least some water, comprising the following steps: a) recording the Raman spectrum of photons scattered by the substance in the wave number range 2500 cm−1 to 4000 cm−1; b) determining, for a given te...

| description | A method of determining the concentration of a salt that may be present in a substance containing at least some water, comprising the following steps: a) recording the Raman spectrum of photons scattered by the substance in the wave number range 2500 cm−1 to 4000 cm−1; b) determining, for a given temperature of the substance, two points of said spectrum corresponding to two specific wave numbers; c) calculating the ratio of two magnitudes representative of said points to obtain a measurement ratio; and d) comparing said measurement ratio to a reference chart representative of the concentration of the salt for various temperatures as a function of the concentration of said salt. The method advantageously requires no taking of samples and may be contactless. |
