Overview
Nitrogen, as an inert gas, has a wide range of applications in various industries. Due to its stable properties and easy access, it is widely used in the food industry. However, as a food additive, it is related to food safety issues. The country has also made special regulations on nitrogen and issued the national standard GB29202-2012 "Food Additive Nitrogen". The National Food and Drug Administration has also responded to the certification issues of food grade nitrogen raised by provincial bureaus. Zirconia gas chromatograph is a gas chromatograph developed specifically for this standard

Zirconia gas chromatograph
★Zirconia gas chromatograph10/100M adaptive Ethernet communication interface with technology * and built-in IP protocol stack enable the instrument to easily realize long-distance data transmission through the enterprise's internal LAN and Internet; Convenient laboratory setup, simplified laboratory configuration, and data management;
★Three independent connection processes are designed inside the instrument, which can be connected to local processing, unit supervisors (such as chief engineer, technical factory director, etc.), and higher-level supervisors (such as environmental protection bureau, technical supervision bureau, etc.), making it convenient for unit supervisors and higher-level supervisors to monitor the operation of the instrument and analyze data results in real time;
★equipped withNETChromTMThe workstation can support multiple chromatography instruments (253 units) working simultaneously, achieving data processing and control, reaching the industry's highest level；
★ *The carrier gas protection and gas path protection functions automatically shut down the instrument's temperature controlled thermal conduction bridge flow in the event of a gas outage. It can prevent thermal conductivity from being damaged in the event of gas interruption, and also prevent the chromatographic column from being burned out in the event of gas interruption, achieving the effect of protecting the chromatographic column.
★ NETChromTMBuilt in workstationModbus/TCPServer, which can easily access the analysis resultsDCS(Distributed Control System);
The instrument adopts vacuum fluorescence display technology, atmospheric，The interface operation is more scientific and reasonable;Having two operating systems in Chinese and English to meet different user needs;
★ InstrumentThe device adopts a modular structural design, which is clear in design, easy to replace and upgrade, and protects the effectiveness of investment;It can meet the analysis of complex samples and can be equipped with various high-performance detectors such as FID, TCD, ECD, FPD, and NPD;
★*Abandoning traditional mechanical valves and pointer pressure gauges! The ability to load EPC technology for gas path control has significantly improved its automation level and overall performance. It has achieved automatic protection for gas path faults, automatic ignition, automatic key shutdown, and automatic execution of gas path opening, achieving one key start;
★ The instrument is designed with a timed self starting program, which can easily complete gasAutomatic online analysis of liquid samples(Sample injection components are required);
★Design the interface for the automatic sampler system to facilitate its connection and future upgrades;
