ST-1545 Chemiluminescence Nitrogen Analyzer
Product Introduction:
The ST-1545 Chemiluminescence Nitrogen Analyzer is an analytical instrument developed by combining chemiluminescence principles with computer technology for measuring total nitrogen content. It is used to determine the total nitrogen content in samples such as crude oil, distillate oil, finished oil, plastics, petrochemicals, and petroleum gas. With extremely high sensitivity, strong anti-interference capability, and accurate analysis results, it complies with SH/T 0657-2007 and ASTM D4629 standards. It is suitable for measuring total nitrogen content in liquids, solids, and gases. Key components of the system use imported parts, ensuring reliable performance and significantly improved sensitivity. It is widely used in power, petroleum, chemical, commodity inspection, universities, and research institutions.
Features:
◆ The instrument uses chemiluminescence to determine total nitrogen content
◆ The instrument can be equipped with liquid samplers, solid samplers, gas samplers, and various nitrogen standards
◆ Key components such as UV lamp, filter, mode dryer, data acquisition card, and photomultiplier tube are imported, ensuring accurate, stable, and high-precision experimental data
◆ Software is user-friendly and efficient, with automatic saving of standard curves and results, ensuring data is never lost
◆ Computer-controlled data acquisition, detection, storage, and printing
◆ Gas flow system includes mass flow meter control and float flow meter control (optional)
◆ Mass flow meter: All gas flows are controlled by electronic mass flow meters, with flow rates set and controlled by computer without manual intervention (optional)
◆ PMT high voltage is adjustable; calibration can be performed using single-point or multi-point calibration, making operation simple and fast
◆ Main components are imported, making the overall performance superior to domestic counterparts, and it can replace imported products
◆ Simple operation with online help to resolve issues promptly; data can be easily accessed, printed, and transmitted
◆ USB communication interface, standard 24-bit data acquisition, detection signal less than 1 microvolt
◆ Exhaust ozone destruction device uses high-temperature pyrolysis instead of traditional activated carbon adsorption, ensuring thorough and fast ozone decomposition
◆ Paid metrology certificate provided by the Institute of Metrology
