|CDR FOODLAB®||CDR FOODLAB® JUNIOR|
|Analyses||Milk and Dairy Products:
Milk Urea Nitrogen (MUN)
Alkaline phosphatase (ALP)
|Configuration with tailored panel of analyses|
|Simultaneous Sample Analyses||16||3|
|Multiple Analyses on a Sample||–|
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.
Test type: End Point
Testing time: 8 minutes
It is possible to carry out several test sessions with a maximum of 16 samples.
Ione ammonio + der. Fenolico 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
The Poligny ACTALIA (France) reference laboratory, specialising in food analysis, performed an evaluation study: the determination of ammonia on whey was performed with CDR FoodLab® and with the enzymatic reference method (NF V 04-217). The correlation between the CDR FoodLab® method and the reference method was found to be good, considering the type of analysis and the difficulty in performing the reference methodology, obtaining an R2 = 0.9265.
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.
Code *300050: 100 tests
Code *300054: 10 tests
The reagents have a shelf-life of 12 months
Use Milk as is
Milk derivatives suitably treated
|NH3 milk||1 - 80 ppm||0.01 ppm||1.23 ppm|
|NH3 cheese||1 - 80 ppm||0.01 ppm||1.37 ppm|
Per campioni con valori di ammoniaca > 80 ppm, utilizzare metà volume di campione (25 uL) e moltiplicare il risultato ottenuto per 2.
