Determination of chloride in water used in brewing proces

CDR BeerLab is the easy, fast and reliable testing system to be used directly at the brewery with no need of expertise in chemical analysis

Chlorides analysis allows, in a simple and fast way, to quantify the concentration of the analyte in the water used in the brewing process.

The systems to test Chloride in water used in brewing process

Chloride levels in the water used in the brewing process can be measured using CDR BeerLab®, a system which enables you to carry out a wide panel of chemical analyses on beer and water, using a single instrument, in a process that is faster and simpler than traditional methods.
With CDR BeerLab® brewers and breweries of any size can independently carry out brewing process controls without having to rely on external laboratories.

Calibration curve

The calibration curve was constructed using standard chloride solutions. The trend of the curve confirmed an excellent linearity of the system over the whole measuring range.

Test Principle

The chloride ions react with the mercuric thiocyanate and release thiocyanate ions. The thiocyanate ions react with Fe (III) giving an orange complex whose intensity, measured at 520 nm, is directly proportional to the concentration of chlorides in the sample.

Reagent test Kits

The reagents are packaged in foil pouches containing 10 tubes useful to perform 10 analyses.

This is the minimum package that allows the use of CDR systems even to those who need to make a few analyses, thus not wasting reagents.

There are also boxes of 100 tests, however, packaged in 10 bags of 10 tubes containing the reagent.

  • Codice *300705 – The kit, designed for 10 tests
  • Codice *300710 – The kit, designed for 100 tests

The reagents have a shelf-life of 12 months.

Processing Sample

Use water as is.
