Technical data sheet
Print- Method description
This method determines the percent of chloride in food products or ingredients by indirect potentiometric back titration of the ions. Salt from a sample is extracted in water. Then, in an acidic environment, the chloride is precipitated with a known amount of silver nitrate. The excess silver nitrate is back-titrated with potassium thiocyanate. The percent of salt can be calculated from the percent of chloride.

- Additional information
This method measures the total amount of chloride ion present in a sample and expresses it as percent of sodium chloride. This method assumes that all of the chloride in the sample comes from sodium chloride. All sources of chloride (CaCl or KCl) present in the sample are titrated, but cations present cannot be differentiated.
Common Salt (Chlorides) Test Testing Questions
We make every effort to keep our methods and detection limits up to date according to the latest standards and qualifications. If you have any questions regarding the limit of detection/quantification or method references, please contact our Customer Service team at 1-800-245-5615.
Our standard turnaround time is 10 business days for most assays. There are some assays that require a longer turnaround time. We also offer a RUSH service that is half the time of the standard turnaround time of the assay at double the cost of the assay. A few assays that we provide cannot be rushed due to the nature of the test. Please check the specific assay you are interested in regarding the ability to RUSH the turnaround time.
