Introduction: GC-9280 Food Grade Nitrogen Chromatograph is a special instrument for analyzing the nitrogen content of food. As an inert gas, nitrogen has a wide range of applications in various industries. Due to its stable nature and easy access, it is also widely used in the food industry. However, as a food additive, it is related to food safety issues. The state has also made special regulations on nitrogen, and has issued the national standard GB29202-2012 "Food Additives Nitrogen". Features: 1. It adopts the advanced 10/100M adaptive Ethernet communication interface and built-in IP protocol stack, so that the instrument can easily realize long-distance data transmission through the enterprise intranet and the Internet; it facilitates the setup of the laboratory and simplifies the Laboratory configuration and data management; 2. Three independent connection processes are designed inside the instrument, which can be connected to local processing, unit supervisors, and superior supervisors (such as Environmental Protection Bureau, Technical Supervision Bureau, etc.), which can easily enable unit supervisors and superior supervisors to monitor the operation of the instrument in real time and Analyze data results; 3. The workstation equipped with the instrument can support multiple chromatographs to work at the same time, realize data processing and reverse control, and reach the industry-leading level; 4. The built-in Modbus/TCP server in the workstation can easily connect the analysis results to DCS (distributed control system); 5. The instrument adopts a color touch screen, high-end atmosphere, and the interface operation is convenient and simple; it has two operating languages, Chinese and English, to meet different user needs; 6. The instrument adopts a modular structure design, which is clear in design, easy to replace and upgrade, and protects the effectiveness of investment; it can meet complex sample analysis, and can be equipped with a variety of high-performance detectors, such as FID, TCD, ECD, FPD and NPD. Wait; 7. Realize the automatic protection of gas circuit failure, automatic ignition, and one-key start; 8. The instrument is designed with a timed self-starting program, which can easily complete the online analysis of gas and liquid samples (requires sample injection parts); 9. The system is designed with an autosampler interface to facilitate the connection of the autosampler and future upgrades; Technical parameter: Temperature control area: 6 channels Temperature control range: 4℃～450℃ above room temperature, increment: 1℃, accuracy: ±0.1℃ Program temperature steps: 16 steps Rising rate: 0.1～39℃/min (normal type); 0.1～80℃/min (high speed type) External events: 8 channels; auxiliary control output 4 channels Types of injectors: packed column injection, capillary injection, six-port valve gas injection, automatic headspace injection optional Number of detectors: 3 (maximum); (FID, TCD, ECD, FPD, NPD) optional Start injection: (manual, automatic, syringe automatic detection) optional Communication interface: Ethernet: IEEE802.3 Hydrogen flame ionization detector (FID) Detection limit: Mt≤3×10-12g/s (n-hexadecane-isooctane solution); Baseline noise: ≤5×10-14A Baseline drift: ≤1×10-13A/30min Linear range: ≥106 Maximum operating temperature: ≤450℃ Thermal Conductivity Detector (TCD) Sensitivity: S≥3500mV?ml/mg (n-hexadecane-iso-octane solution) (1, 2, 4, 8 times magnification optional) Baseline noise: ≤10μV Baseline drift: ≤30μv/30min Linear range: ≥104 Electron Capture Detector (ECD) Detection limit: ≤1×10-14g/s (propane hexahexahexa-isooctane solution) Baseline noise: ≤0.03mV Baseline drift: ≤0.2mV/30min Linear range: ≥104 Radioactive source: Ni63 Flame Photometric Detector (FPD) Detection limit: (S)≤5×10-11g/s; (P)≤1×10-12g/s (methyl parathion-absolute ethanol solution) Baseline noise: ≤0.03mV Baseline drift: ≤0.2mV/30min Linear range: ≥103(S) 102(P) Nitrogen Phosphorus Detector (NPD) Detection limit: (N)≤1×10-13g/s; (P)≤5×10-14g/s (azobenzene-malathion-isooctane solution) Baseline noise: ≤0.03mV Baseline drift: ≤0.2mV/30min Linear range: ≥102(N) 103(P)
