SH708 Chemiluminescence Nitrogen Determination Instrument
The SH708 chemiluminescence nitrogen analyzer uses the chemiluminescence method to determine the total nitrogen content, which improves the ability to resist impurity interference and avoids the cumbersome operation of the titration cell caused by the coulometric method and the resulting unstable factors, greatly improving the sensitivity of the instrument. The key components of the system use imported components, ensuring reliable performance of the entire machine. Applicable to the determination of total nitrogen content in paraffin oil, diesel, gasoline, lubricating oil, fuel oil, liquefied gas, and natural gas, as well as other oil products, chemical raw materials, and finished products, in accordance with the standard SH/T 0657 Determination of Trace Nitrogen in Liquid Petroleum Hydrocarbons (Oxidative Combustion and Chemiluminescence Method, ASTM D5762-2017, SH/T 0704, ASTM D4629, GB/T 17674 Determination of Nitrogen Content in Crude Oil by Boat Injection Chemiluminescence Method).
Performance characteristics
● The use of pneumatic support instrument cover, open the instrument cover internal structure at a glance.
● The front shape and repeatability of low and small content are better.
● The instrument can be continuously switched on for 24 hours continuous use of accurate chemiluminescence nitrogen determination instrument.
● The total nitrogen content in the sample was rapidly measured by chemiluminescence method.
● High-precision data acquisition and the application of computer technology provide a reliable guarantee for data acquisition, control and processing.
