Abstract
The analytical method of total nitrogen content in crude oil evaluation has been introduced. The analytical results are precise and reliable using ANTEK 9000 chemiluminescence azotometer and working curve method, uniform injecting from an automated sampling system. The relative standard deviation can meet the ASTM standards, and the result is providing a scientific basis for crude oil evaluation.
