Summary
The instrument is designed and manufactured according to the standards SH/T 0689-2000 Standard test method for determination of total sulfur in light hydrocarbons,motor fuels and oils by ultraviolet fluorescence,SH/T 0657-2007 Standard test method for trace nitrogen in liquid petroleum hydrocarbons by syringe/inlet oxidative combustion and chemiluminescence detection and ASTM D 5453 -2006 standard.It is widely used in petroleum,chemical industry,electric power,coal,food,environment proection and others.At present,SY-0689N is the advanced instrument to analyze the sulfur,nitrogen in China.
I.Main technical characteristics
1. The instrument can detect the both sulfur and nitrogen,also could test the solid sample or liquid sample.
2. With the desktop computer,Windows system,man-machine direct conversation platform,It can set all prameters and make the test by the keyboard operation.
3. It adopts the control technology of the computer to automatically collect,process,store and print all data.with the wide linearity range of measurement,strong capacity of resisting disturbance,easy operation and reliable test results.
4. With the imported fluorescence excitation source,membrane desiccator,optical filter,metal encapsulated photomultiplier,It has the features of the high sensitivity,fast,stability,high precision,good consistency.
5. With the advanced temperature control system,fast and steadily warming rate,long service life,the temperature control accuracy ±3ºC during the temperature range,It can meet the test requirements.
