n setting specification for determining the total nitrogen content in aromatic hydrocarbons.
This test method requires the use of reduced pressure at the detector. Loss of vacuum or pressure fluctuations impact the sensitivity of the detector and the ability to determine nitrogen concentrations less than 1 mg N/kg.
1. Scope
1.1 This test method covers the determination of total nitrogen in aromatic hydrocarbons, such as benzene, toluene, and xylene.
1.2 This test method is applicable for samples
