KR08 model total nitrogen content analyzer is designed according to ASTM D4629 standard, it can used for paraffin oil, diesel, gasoline, lubricating oil, fuel oil, liquefied gas and natural gas, as well as other oils, chemical raw materials and finished products.
The KR08 oil nitrogen analyzer uses the chemiluminescence method to determine the total nitrogen content, which improves the ability to resist impurity interference, avoids the complicated operation of the titration cell and the unstable factors caused by the electricity method, which greatly improves the sensitivity of the instrument. . The key components of the system use imported components, which makes the performance of the whole machine reliable. Applicable to the determination of total nitrogen content of paraffin oil, diesel, gasoline, lubricating oil, fuel oil, liquefied gas and natural gas, as well as other oils, chemical raw materials and finished products, and the determination of trace nitrogen in liquid petroleum hydrocarbons by standard SH/T 0657 (Oxidative Combustion and Chemiluminescence Method), ASTM D4629, GB/T 17674 (Determination of Nitrogen Content in Crude Oil by Boat Injection Chemiluminescence Method).
Performance characteristics
1. Use the pneumatic support to support the upper cover of the instrument, the internal structure of the the instrument is very clear when open the upper cover.
2. The repeatability for low content and small content is better.
3. The instrument can continuously use for 24 hours.
4. The total nitrogen content in the sample is rapidly measured by chemiluminescence.
5. High-precision data acquisition and application of computer technology provide a reliable guarantee for data collection, control and processing.
