Combustion and chemiluminescence determination of the nitrogen content of the samples TN-3000-type analyzer by oxidation of sulfur and nitrogen. Determination of process control and process by computer, stable and reliable performance, analysis of high accuracy, good repeatability, flexible operation, can replace imported. By increasing the TS-3000 Sulfur content detection module can be upgraded to TSN-3000 type of sulfur and nitrogen analyzer, samples of sulfur and nitrogen were detected simultaneously. Specifications: l implementation of the standards:?? SH / T 0657-2007 (equivalent to ASTM D4629-02) Determination of Trace Nitrogen in Liquid Petroleum Hydrocarbons (oxidation combustion and chemiluminescence) SH / T 0704-2001 Petroleum and petroleum products Determination of nitrogen content (boat injection chemiluminescence) GBT 17674-1999 crude oil and its nitrogen content in the measurement (chemiluminescence) l Determination of product:? Chemiluminescence l sample types: liquid, solid, gas l sample Injection volume: solid: 1 ~ 30mg, liquid: 5 ~ 30μL, gas: 1 ~ 10mL l measuring range: 0.1 ~ 5000mg / L l detection limit: 0.1mg / L l Temperature range: room temperature ~ 1100 ℃ l Accuracy: 0.5% ± 5 ℃ l Air source: Argon: purity 99.995% oxygen purity: 99.99% l Power: AC220V, 50Hz l Maximum Power: 1600W l Dimensions: Host: 420 × 400 × 530 (mm) Temperature Control: 500 × 400 × 530 (mm) l Weight: Host: 20kg, temperature: 30kg Main features: l High sensitivity: The key components imported components, which makes the performance has been a reliable guarantee. l repeatability: Once the calibration curve, for long-term use, reduce error due to chance to bring different operator calibration. l Safety and environmental protection: do not use wet chemistry needed for a variety of chemical reagents, greatly reducing operator workload. Staff without exposure to chemical agents, the entire testing process does not produce toxic substances. l simple: a Windows-based Chinese user interface, making the operation more convenient and faster. Computer control of all parameters, condition selection, data acquisition, processing, storage and printing. l Complete configuration: Host, temperature control systems, computers, printers, automatic liquid sampler l Other options: solid injector, a gas injector USB Interface:? use USB interface to connect the computer and the system host, convenient and flexible, adapt to all kinds of computers. ? Performance can improve: to meet the special requirements of users, the detection limit of the instrument was increased to 0.02mg / L. Measuring range can be extended to 0.02mg / L ~ 2%.
