Chloride test in milk, cheese and aqueous solution

The chemical analysis of the milk and dairy products for quality control for every stage of the production chain with CDR FoodLabThe chloride test allows to identify any added salt water in the milk, a sophistication that the normal cryoscopic examination does not detect. This analysis allows to quantify the concentration of salt in products such as cheese, vegetable purees and sauces, and liquid of processing and storage of dairy products.

It is not necessary skilled staff nor a laboratory for the analysis.
Results are correlated with reference method results.
It is free of service and maintenance cost.
With the same analyzers you can also perform analysis of egg, tomato, vegetable purees, cheeses and fats.

Method

Test type: End Point
Time of test: 3 minutes
It is possible to carry out several test sessions with a maximum of 16 samples.

Test principle

Cl + Hg(SCN)2 + Fe3+freccia Orange colored complex

Chloride ions react with mercuric thiocyanate and form thiocyanate ions. The thiocyanate ions react with the Fe (III), giving an orange-colored complex whose intensity, measured at 505 nm, is directly proportional to the concentration of chlorides in the sample.

Calibration curve

Comparative tests, on samples of whole milk performed between the reference method and the CDR FoodLab® method, made in a leading milk production company, have confirmed a very good alignment between the two systems.

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.

Reagent test kit *300100: suitable for 100 tests

Reagent test kit *300104: suitable for 10 tests

The reagents have a shelf-life of 12 months.

 

For vegetable puree the code is:

Reagent test kit *300200: suitable for 100 tests

Reagent test kit *300204: suitable for 10 tests

The reagents have a shelf-life of 12 months.
