Sodium Hydrosulfide solution

Sodium Hydrosulfide solution.

The concentration of a solution refers to the amount of solute contained in a given quantity of solution (or solvent). Common determination methods include titration, laboratory instrumental analysis, and density measurement. However, these methods suffer from delayed test results, making it impossible to adjust solution concentrations in a timely manner during production, which can compromise industrial product quality. As production processes place increasingly stringent demands on concentration measurement, the accuracy of these measurements directly impacts process quality.
Refractometer-based concentration analyzers operate on the principle that light travels at different speeds in different media, causing its direction to change when passing from one medium to another—a phenomenon known as refraction. Under specific conditions, the concentration of a medium is correlated with its refractive index. In practical applications, the concentration of a medium can be determined by measuring the critical angle of refraction.
