Determination Of Trace Nitrogen In Liquid Petroleum Hydrocarbons SH708 Chemiluminescence Method

SH708 Chemiluminescence Nitrogen Analyzer
The SH708 chemiluminescence nitrogen analyzer adopts the chemiluminescence method to determine total nitrogen content. It enhances resistance to impurity interference, eliminates unstable factors caused by the titration cell locking operation in the coulometric method, and significantly improves the instrument sensitivity.
Key system components are imported to ensure reliable performance of the entire unit.
The analyzer is suitable for the determination of total nitrogen content in petroleum products, chemical raw materials and finished products, including paraffin oil, diesel fuel, gasoline, fuel oil, lubricating oil, liquefied petroleum gas (LPG) and natural gas.
It complies with the following standards:
SH/T 0657: Determination of trace nitrogen in liquid petroleum hydrocarbons (Oxidative combustion and chemiluminescence method)
ASTM D4629
GB/T 17674: Determination of nitrogen content in crude oil (Boat injection chemiluminescence method)
Chemiluminescence Method Trace Nitrogen Content Analyzer in accordance with ASTM D4629 and ASTM D5762
Ultraviolet Fluorescence Sulfur & Nitrogen-in-Oil Analyzer
Ultraviolet Fluorescence Total Sulfur & Nitrogen-in-Oil Analyzer for Light Hydrocarbons, ASTM D5453
ASTM D5453 Ultraviolet Fluorescence Sulfur & Nitrogen-in-Oil Analyzer
The performance characteristics of
1, the use of pneumatic support instrument cover, open the instrument cover internal structure at a glance.
