KJ-601A Gas Chromatograph

The KJ-601A gas chromatograph is a high-end analytical instrument that integrates high precision, intelligence, and multi-functionality. It comes with PC software and an in-built chromatography workstation, enabling two-way synchronous control between the PC end and the host touch screen. The operation is convenient and efficient. The instrument uses high-precision valve meters to control the flow rate and can be paired with a high-precision liquid automatic sampler. All its performance and technical indicators have reached the international leading level. With its modular design, strong detection capabilities, and flexible adaptability, it is widely used in fields such as petroleum, chemical industry, environmental protection, food safety, disease control, education and research, etc. It can accurately complete the quantitative, semi-quantitative, and trace analysis of organic substances, inorganic substances, and gases, providing reliable detection support for quality control and scientific research in various industries.

Application Scenarios

● Petrochemical industry: Used for component analysis of petroleum products such as crude oil, gasoline, diesel, and lubricating oil, to detect hydrocarbon components, additive content, impurity content (such as sulfur and nitrogen compounds), monitor the stability of production processes, and ensure that the products comply with national standards; it can also be used for purity testing of chemical raw materials (such as methanol, ethanol, benzene series), as well as tracking analysis of intermediate products during reactions, helping to optimize production processes.

 

● Environmental monitoring scenarios: Suitable for the detection of samples such as ambient air, industrial waste gas, surface water, groundwater, and wastewater. It can accurately detect pollutants such as VOCs (volatile organic compounds), benzene series, polycyclic aromatic hydrocarbons, halogenated hydrocarbons, etc., meeting the requirements of environmental emission compliance monitoring, environmental quality evaluation, and pollution source tracing, in accordance with the "Integrated Emission Standards for Air Pollutants" and "Integrated Emission Standards for Wastewater".

 

● Food safety field: Used for the detection of harmful substances in food and food additives, such as pesticide residues (organophosphorus, organochlorine), veterinary drug residues, food additives (preservatives, sweeteners), plasticizers, volatile flavor substances, etc., and can also detect the migration substances in food packaging materials, ensuring food safety and assisting enterprises in compliant production and regulatory agency inspections.

 

● Disease control and pharmaceutical field: Can detect drug metabolites and toxins in human blood and urine (such as heavy metal derivatives, organic toxins), providing data support for clinical diagnosis and poisoning emergency treatment; it can also be used for drug research and quality control, detecting the content of active ingredients and impurities (such as related substances) in drugs, meeting GMP management requirements, and ensuring the quality and safety of drugs.

 

● Education and research scenarios: Suitable for teaching and research work in professional fields such as analytical chemistry, environmental science, and materials science in universities and research institutions. It can carry out organic substance separation, component analysis, and qualitative and quantitative research of unknown substances, support the coordinated operation of multiple instruments, and help promote scientific research projects and talent cultivation.

 

● Other industry scenarios: Also applicable in fields such as new energy (such as component detection of lithium battery electrolyte), metallurgy (such as rare gas analysis), cosmetics (such as component analysis of fragrances and flavors), and tobacco (such as nicotine and tar content detection). It can be customized for specific detection tasks based on different industry requirements, by combining corresponding detectors and sampling methods.
