Gas Chromatography

Introduction to GC-460PLUS gas chromatograph: Gas chromatograph is an analytical tool widely used in multiple fields, and its main applications include: Petroleum and petrochemical analysis: involves chemical analysis, crude oil analysis, refinery gas analysis, simulated distillation, oil analysis, elemental hydrocarbon analysis, sulfur/nitrogen/oxygen compound analysis, gasoline additive analysis, fatty hydrocarbon analysis, aromatics analysis, and other aspects in oil and gas field exploration. Environmental analysis: including analysis of atmospheric pollutants, water, soil, solid waste, etc. Food analysis: including pesticide residue analysis, essence and flavor analysis, additive analysis, fatty acid methyl ester analysis, food packaging material analysis, etc. Drug and clinical analysis: such as estriol analysis, catecholamine metabolite analysis, urine progesterone and progesterone analysis, plasma testosterone analysis, blood ethanol/anesthetic and amino acid derivative analysis, etc. Pesticide residue analysis: involves analysis of organochlorine pesticide residues, organophosphorus pesticide residues, insecticide residues, herbicide residues, etc. Fine chemical analysis: including additive analysis, catalyst analysis, raw material analysis, product quality control, etc. Polymer analysis: involves monomer analysis, additive analysis, copolymer composition analysis, polymer structure characterization/impurity analysis in polymers, thermal stability research, etc. Synthetic industry: including applications in method research, quality monitoring, process analysis, etc. In addition, gas chromatographs are widely used in other fields。

The GC-460PLUS gas chromatograph is an improvement on the basis of the GC-460 back control gas chromatograph, which enhances the display interface, detector sensitivity, and modular design to replace components without being cumbersome. Technical characteristics of GC-460PLUS gas chromatograph: A newly designed automatic gas chromatograph. The host adopts a 7-inch color touch screen, with a user-friendly human-machine exchange interface. The computer reverse control and the host touch screen achieve synchronous bidirectional control. A multi-core, 32-bit embedded hardware system ensures the reliable operation of the instrument. The synchronous external triggering function can be triggered by external signals (such as automatic samplers, thermal analyzers, etc.) to simultaneously start the host and workstation. Equipped with comprehensive system self inspection function and automatic fault identification function. The host has 20 methods for storing memory functions, which can be directly called when needed, making it very convenient. It has an extended functional interface with 8 external events, and can be equipped with various control valves to work according to its own set timing. The external connection method is through Ethernet port connection (RJ45), providing convenience for remote control of data.
