SH708 Chemiluminescence nitrogen analyzer

The SH708 chemiluminescence nitrogen analyzer uses chemiluminescence method to determine the total nitrogen content, which improves the ability to resist impurity interference, avoids the complicated operation of the titration cell caused by the electric method, and greatly improves the sensitivity of the instrument. The key components of the system are imported, ensuring reliable performance of the entire machine. Suitable for determining the total nitrogen content of 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. It follows the standard SH/T 0657 for the determination of trace nitrogen in liquid petroleum hydrocarbons (oxidation combustion and chemiluminescence method, ASTM D5762-2017, SH/T0704, ASTM D4629, GB/T 17674 for the determination of nitrogen content in crude oil by boat injection chemiluminescence method).

Performance characteristics

Using pneumatic support to support the instrument cover, the internal structure of the instrument cover can be easily seen when opened.

Low and low content peaks have better shape and repeatability.

The total nitrogen content in the sample is rapidly measured by chemiluminescence method.

The application of high-precision data acquisition and computer technology provides reliable guarantees for data collection, control, and processing.
