Product Description

SH708 chemiluminescence nitrogen determination instrument using chemiluminescence method to determine the total nitrogen content, improve the ability of anti-impurity interference, avoid the electric quantity method of titration cell lock operation and thus bring unstable factors, so that the sensitivity of the instrument is greatly improved.

The key components of the system are imported, which ensures the performance of the whole machine reliably.

Is suitable for the determination of paraffin oil, diesel oil, petrol, fuel oil, lubricating oil, liquefied petroleum gas and natural gas, and other oil products, chemical raw materials and finished product of the total nitrogen content, implement standard SH/T 0657 trace nitrogen in liquid petroleum hydrocarbons assay (oxidation burning and chemiluminescence method, ASTM D4629, GB/T 17674 the determination of nitrogen content in the crude oil boat injection chemiluminescence method.

Chemiluminescence Method Trace Nitrogen Content Analyzer as Per ASTM D4629 and ASTM D5762

Ultraviolet Fluorescence Sulfur, Nitrogen-in-Oil Analyzer

Ultraviolet Fluorescence Total Sulfur in Light Hydrocarbons Nitrogen-in-Oil Analyzer ASTM D5453

ASTM D5453 Ultraviolet Fluorescence Sulfur,Nitrogen-in-Oil Analyzer

Ultraviolet Fluorescence Total Sulfur in Light Hydrocarbons Nitrogen-in-Oil Analyzer ASTM D5453

The performance characteristics of

1, the use of pneumatic support instrument cover, open the instrument cover internal structure at a glance.

2. The front shape and repeatability of low and small content are better.

3, the instrument can be continuously switched on for 24 hours continuous use of accurate chemiluminescence nitrogen determination instrument.

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

5. High-precision data acquisition and the application of computer technology provide a reliable guarantee for data acquisition, control and processing.
