Determination of solfate in water used in brewing proces
Sulfate 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 Sulfate in water used in brewing process
Sulfate 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.

Method
Test type: End Point.
Time testing: one test 1 minutes.
Are possible test sessions with several samples, up to 16 for CDR BeerLab® and 3 for Junior CDR BeerLab®
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 sulfate ion reacts with barium chloride to form barium sulfate. The absorbance determined at 420 nm is proportional to the amount of analyte present in the water 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 *300685 – The kit, designed for 10 tests
- Codice *300690 – The kit, designed for 100 tests
The reagents have a shelf-life of 12 months.
Processing Sample
Use water as is.
