Nitrite in Coolants
Method Abstract #13
Scope and Application
This application is used for determination of nitrite concentration in coolant samples. There are no known methods of conformity.
Nitrite concentration is determined by titration with ceric sulfate using a redox electrode. The sample is titrated until a strong endpoint is reached.
Sample Titration Curve
|Measuring Range*||300 – 1500 ppm|
|RSD for 1000 ppm Standard||2.34% or +/- 23.42|
*Data for this measuring range was obtained using laboratory prepared standards formulated from potassium chloride. The measuring range may be increased by using larger capacity analysis vessels and/or auto-dilution.
