Ammonia test in milk

The chemical analysis of the milk and dairy products for quality control for every stage of the production chain with CDR FoodLabThe ammonium ions react with a phenolic derivative and form a blue-green colored complex whose intensity, measured at 700 nm, is directly proportional to the concentration of ammonia in the sample.

Testing time: 8 minutes
It is possible to carry out several test sessions with a maximum of 16 samples.

Test priciple

Ione ammonio + der. Fenolico freccia blue/green complex

The ammonium ions react with a phenolic derivative and form a blue-green colored complex whose intensity, measured at 700 nm, is directly proportional to the concentration of ammonia in the sample

Calibration curve

Comparative tests, on samples of whole milk, performed between the reference method and the FOODLAB method, made in a leading company of production of milk, have confirmed a very good correlation 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 *300050 suitable for 100 tests

Reagent test kit *300054 suitable for 10 tests

The reagents have a shelf-life of 12 months.

Processing – Sample volume – Measuring range

Sample
Use Milk as is
Milk derivatives suitably treated

Measuring range
(ppm di ammonia)
Sample volume Resolution
(ppm di ammoniaca)
Repeatability
1 – 80 50 µL 0,1 3 ppm

Per campioni con valori di ammoniaca > 80 ppm, utilizzare metà volume di campione (25 uL) e moltiplicare il risultato ottenuto per 2.
