CDR BeerLab® - simple, fast and reliable analysis system of beer.

Determination of Total sulfur dioxide (SO₂) in Beer

CDR BeerLab® allows to determine Total sulfur dioxide (SO2) in beer giving the result in 2 minutes, avoiding the time-consuming distillation of the EBC reference method and the using of dangerous and cancerogenic compounds used by AOCS reference method.

You can use CDR BeerLab® method easily in the QC lab or even at production line.

SO2 is naturally produced in the fermentation steps of beer production. The legal limit is 10 mg/L.

Method

Test Principle

Total SO₂ reacts with a specific cromogen forming a compound used to follow the reaction itself. The end point of the reaction is read at 430 nm and the increasing of absorbance is proportional to the total SO₂ concentration.
