Acetaldehyde (Ethanal) analysis in wine and must

CDR WineLab® analysis system fast, simple to use and reliable for determining multiple parameters in wine and mustAcetaldehyde, in alkaline environment, is oxidized enzymatically to acetic acid with the consequent production of NADH. The increasing of the absorbance, measured at 366 nm in end-point, is proportional to the concentration of acetaldehyde in the sample.

The Analyzers CDR WineLab® for determining Acetaldehyde (Ethanal) in Wine and Must

The system is supplied pre-calibrated and ready for use.
Results are expressed in accordance with the reference method.
It is also possible to standardize the system using samples with a known titration.
The reagents have a shelf-life untill 18 months
The analytical methods are simple: the system does not require an equipped laboratory or skilled staff.

Method

Test type: End Point.
Testing time: one test 6 minute – 50 Test/Hour
Test session with several samples is possible up to a maximum of 16.

Calibration curve

The calibration curve of CDR WineLab®, obtained using reference methods, potentiometric titration, confirms the excellent linearity of the system over the whole testing range.

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. *300417 : 10 tests 

Code. *300415: 100 tests (10 packages of 10 tests)

The reagents have a shelf-life of 4 months

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.
