Determination of the Copper in wine

CDR WineLab® is the fast, simple and reliable wine analysis system to be used right in the winery with no need of qualified personnel in the field of chemical assays

The must always contains relatively high doses of copper deriving from downy mildew treatments. It is well known that excess copper is reduced during the fermentation process. Sometimes the copper level can low down too low levels, especially in white wines. This low copper concentration can lead the reduction problems that can arise, to the opening of the bottle, the typical reduction off-flavour bringing serious commercial problems to the bottle producer.

Analysis sessions with multiple samples up to a maximum of 16 are possible.

Calibration Curve

The calibration curve of the CDR WineLab® instrument was made using standard copper solutions. The curve obtained confirmed an excellent linearity of the system on both measurement ranges

Copper in Wine CDR WineLab® Calibration Curve.

Test Principle

The copper content is determined by its reaction with a chromogen which develops a colour change, whose optical intensity measured at 620nm, is proportional to the copper concentration in the sample analyzed. 

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 *300577: 10 tests

Code *300575: 100 tests

The reagents have a shelf-life of 6 months

Processing Sample

If necessary, the sample shall be degassed using the specific ultrasonic bath (code 222062). In case of tests performed on must, the sample shall be first centrifuged (code 222061).

Measuring Range

Test Measuring Range Resolution Repeatability
Copper [0.05-0.70] ppm 0.05 - 0.7 ppm 0.01 ppm 0.04 ppm
Copper [0.6-1.20] ppm 0.6 - 1.2 ppm 0.01 ppm 0.09 ppm

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.
