CDR WineLab® the reliable, complete and fast system of wine analyses

Determination of chlorides in vinegar

The chloride test allows to identify the amount of sodium chloride in the vinegar.

Method

Test type: End Point.
Time testing: 5 minutes.
Analysis sessions with multiple samples are possible up to a maximum of 16 tests for CDR WineLab® and 3 tests for CDR WineLab® Junior.

Sample treatment

Use vinegar as is. If necessary, the sample should be centrifuged (code 222061) or filtered (code 300210).

Test Principle

Chloride ions react with mercuric thiocyanate and form thiocyanate ions. The thiocyanate ions react with the Fe (III), giving an orange-colored complex whose intensity, measured at 505 nm, is directly proportional to the concentration of chlorides in the sample.

Calibration curve

Comparative tests, on samples of vinegar performed between the reference method and the CDR WineLab® method, made in a leading vinegar production company, have confirmed a very good alignment between the two systems.
