DSHD-0657 Nitrogen Chemiluminescence Analyzer
Product Description
DSHD-0657 Nitrogen Chemiluminescence Analyzer
Summary
This instrument is designed and made as per industrial standard SH/T 0657－2007Standard test method for trace nitrogen in liquid petroleum hydrocarbons by syringe/inlet oxidative combustion and chemiluminescence detection. It is widely used in petroleum, chemical, electricity, coal, food, environment and other fields. Standards: SH/T 0657－1998，ASTM D4629－2010，SH/T 0704-2001，ASTM D5762 -2010, ASTM D6069-2001，GB/T 17674-1999.
I. Main technical features
1.High sensitivity
The TN-3000 determine the total nitrogen content by chemiluminescence，improves the ability of anti-jamming, to avoid complicated operation of titration pool and factors of instability which used Coulometry. So the sensitivity of the instrument is greatly improved. The key components of the system use imported components and makes the machine has a reliable guarantee.
2.Easy to operate
Based on Windows ( 7 , XP , Me, 98 ) Chinese user interface to make the operation more convenient and fast.. You only need to click the mouse, and it can complete all of the parameter settings. The data collecting, processing, storage and printing controlled by computer.
3.System configuration
Standard configuration：Printer＋Computer＋TN-3000＋Liquid injector
Other optional parts：Solid injector、Gas injector
