Nitrogen Chemiluminescence Analyzer

Summary

  This instrument is designed and made as per industrial standard SH/T 0657－2007Standard test method for trace nitrogen in liquid petroleum hydrocarbons by syringe/inlet oxidative combustion and chemiluminescence detection. It is widely used in petroleum, chemical, electricity, coal, food, environment and other fields. Standards: SH/T 0657－1998, ASTM D4629－2010, SH/T 0704-2001, ASTM D5762 -2010, ASTM D6069-2001, GB/T 17674-1999.

I. Main technical features
