Product Overview & Applications

The HM9890 is a gas chromatograph (GC), a high-precision laboratory instrument designed for the separation and quantitative analysis of volatile compounds. It separates complex mixtures into individual components and accurately determines the concentration of each component. It is suitable for measuring dissolved gas components in insulating oil within electrical systems. It can simultaneously detect seven gas components in insulating oil: H₂, CO, CO₂, CH₄, C₂H₄, C₂H₆, and C₂H₂ (hydrogen, carbon monoxide, carbon dioxide). It provides complete analysis of methane, ethylene, ethane, and acetylene content, with acetylene's minimum detectable concentration being 0.06 ppm.
Application Areas:
1. Power and Energy: Dissolved Gas Analysis (DGA) in transformer oil
2. Petrochemicals: Component analysis of crude oil, refined petroleum products, and chemical feedstocks
3. Environmental Monitoring: Organic pollutants (VOCs, SVOCs) in air, water, and soil
4. Food Safety: Detection of pesticide residues, additives, and flavor components in food
5. Pharmaceuticals and Health: Drug purity, impurity content, and biological sample analysis

Features & Advantages
★ Features a 10/100M adaptive Ethernet communication interface for long-distance data transmission;
★ Incorporates three independent connection processes internally, enabling supervisors and senior supervisors to monitor instrument operation and analyze results in real time;
★ The networked workstation supports simultaneous operation of multiple chromatographs (up to 253 units), enabling data processing and remote control. This streamlines documentation management while significantly reducing laboratory investment and operational costs;
★ Remote diagnostics and software updates are available (user permission required);
★ Features a 5.7-inch color LCD screen for versatile user operation;
★ Includes dual Chinese and English operating systems with seamless switching;
★ Employs multi-processor parallel operation with optional high-performance detectors (e.g., FID, TCD), supporting up to three detectors simultaneously;
★ Modular structural design ensures clear configuration;
★ Innovative microprocessor-based temperature control system with six fully independent temperature channels, supporting sixteen-step programmed temperature ramping; incorporates an automatic column oven rear door system for accelerated heating/cooling rates;
★ Instrument features a scheduled auto-start function.
★ Chromatograph incorporates a low-noise, high-resolution 24-bit AD circuit with baseline storage and baseline subtraction capabilities;
★ Instrument comes equipped with a mainstream domestic "Transformer Oil Gas Analysis Workstation" offering powerful functionality and intuitive operation.
