Will the indigo method for ozone work with carbonated samples?
Ozone testing on carbonated samples
The indigo method for ozone (method 8311) should not be used with carbonated samples. The AccuVac® amplues will pull the gas out of the sample before filling the AccuVac® with water and therefore will not completely fill. This will negatively impact results. Beverage companies that want to test ozone should test the sample after ozonation but before the carbonation process.
