IP 379 - Total Nitrogen
We perform fuel quality testing by IP 379 to determine trace quantities of nitrogen in hydrocarbons. The detection limits are 0.3 to 100 ppm. The method uses an oxidative instrument and chemiluminescence detection.
We also test for nitrogen by ASTM D3228 and ASTM D4629. These different test methods use different instruments or procedures or are used for certain sample types. Click on the test method number to learn more about each test.
