CHEMetrics offers test kits employing the well-known Mercuric Nitrate and Ferric Thiocyanate Methods to deliver sensitivity and accuracy within two minutes or less. Based on CHEMetrics patented Self-Filling Reagent Ampoule technology. Premixed. Premeasured. Precise. Each kit contains 30 tests.

The Mercuric Nitrate Method

CHEMetrics employs a mercuric nitrate titrant in acid solution with diphenylcarbazone as the end point indicator. Results are expressed as ppm (mg/l) Cl-.

Contains mercury.  Dispose according to county, national or EU laws.

The Ferric Thiocyanate Method

The Chloride Vacu-vialsĀ® test employs the ferric thiocyanate chemistry. Chloride reacts with mercuric thiocyanate to liberate thiocyanate ion. Ferric ion reacts with thiocyanate ion to produce an orange-brown thiocyanate complex in proportion to the chloride concentration. Results are expressed as ppm (mg/l) Cl-.

Contains mercury.  Dispose according to county, national or EU laws.

Applications

Chloride is the most common inorganic anion found in water and wastewater. Chloride levels in drinking water are kept relatively low to limit corrosion and adverse taste. The Indicator Parametric Value for chloride in drinking water in the UK at the supply point is 250 mg/l (ppm). The Indicator Parametric Value for chloride in drinking water in Ireland is 250 mg/l (ppm). Natural sources of salt are the ocean and various salt deposits above and below ground. Chloride is very corrosive to most metals in systems with elevated pressures and temperatures such as boilers and oil-drilling equipment.
