ASTM D4629 - Nitrogen Content in Liquid Petroleum Hydrocarbons


We perform testing by ASTM D4629 to determine trace quantities of nitrogen in hydrocarbons; this test is called Total Nitrogen.  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 IP 379. 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.
