Zinc analysis on wort

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

Zinc analysis allows, in a simple and fast way, to quantify the concentration of the analyte in the wort during the production process.

Zinc is an indispensable element for the correct activity of yeasts and therefore measuring its concentration allows to avoid fermentation issues.

The analyzers to test of Zinc in wort

The zinc on wortcan 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: 6 minutes.
Are possible test sessions with several samples, up to 16 for CDR BeerLab® and 3 tests for CDR BeerLab® Junior.

Calibration Curve

The calibration curve was created compared to reference method ICP-MS. The trend of the curve confirmed an excellent linearity of the system over the whole measuring range.

The calibration curve for zinc analysis with CDR BeerLab® was constructed by comparison with the reference method ICP-MS. [0.9-10] R² = 0.9951 - [0.1-1] R² = 0.9632

Test Principle

Zinc reacts in an alkaline environment with a chromogen to form a colored complex, whose absorbance measured at 578 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.

Code *300995: 10 tests

Code *300990: 100 tests (10 packages of 10 tests)

Processing Sample

Use on wort. Centrifuge the sample before analysis with the appropriate centrifuge. In case of CO₂, degas the sample with the ultrasonic bath.

With the CDR system, you can perform your tests in total autonomy

Neither skilled staff nor a dedicated external laboratory is needed to use our systems. CDR FoodLab® optimizes traditional testing methods, making them faster and easier, while guaranteeing accuracy standards in line with the reference methods.

Analytical kit

CDR FoodLab® Analysis Systems use disposable pre-vialed reagents specifically developed by the research laboratories of CDR. The use of pre-vialed reagents and the analytical procedures allow:

  • a sample preparation that is quick and easy, when needed at all;
  • making analytical procedures extremely fast and easy;
  • removing all needs for complex calibration procedures.

Reagents come in aluminum packages containing 10 test tubes each to perform 10 tests (or packages for 100 tests containing 10 single packages of 10 test tubes each).

Just a few steps and results are yielded right away

Just a few steps will suffice to carry out your analysis in a rapid way in total autonomy. The system is composed of both the analyzer based on photometric technology and a kit of low toxicity, pre-vialed reagents, developed by CDR.

CDR FoodLab® is cost-effective because it does not require the use of expensive equipment and does not entail maintenance, assistance or calibration costs.
