Chloride dosage

Chloride (CAS No. 16887-00-6) is an essential mineral ion naturally present in water, soils, and many food products. Its analysis allows for the quantification of Cl⁻ ion content in various media—whether drinking water , food , cosmetic products , chemical formulations , or nutraceutical preparations .

This measurement is essential for salinity control , chemical stability monitoring , and assessing the ionic charge . It also helps verify regulatory compliance in the fields of food , the environment , and pharmacopoeia .

Analytical methods: argentometry, potentiometry and ion chromatography

Chloride ion concentration can be determined using various analytical methods:

• Argentometry (Mohr's method) : direct titration with a silver nitrate solution and chromate indicator, for simple aqueous samples.
• Potentiometry : electrochemical measurement using a silver-selective electrode, suitable for complex matrices.
• Ion chromatography (IC) : simultaneous separation and quantification of anions (Cl⁻, NO₃⁻, SO₄²⁻), offering excellent accuracy for multionic analyses.

These methods comply with ISO 9297 , NF EN ISO 10304-1 and NF T90-015 , ensuring the reliability, traceability and comparability of the results .

Industrial and regulatory applications

Chloride analysis is used in many sectors:

• Drinking and industrial water : control of salinity and compliance with regulatory thresholds (directive 98/83/EC).
• Food industry : monitoring of salt in processed products, broths, sauces, butters or mineral waters.
• Nutraceuticals and animal nutrition : verification of ionic and mineral intake in formulations.
• Cosmetics and chemistry : control of the stability of solutions and ionic formulations.
• Environment : monitoring of saline contamination in surface waters or soils.

This service can be complemented by the measurement of sodium (Na⁺) or potassium (K⁺) for a complete characterization of the ionic profile .
