English Version:
GC3900 Gas Chromatograph is a specialized analytical instrument developed for alcohol content detection in the beverage industry. Incorporating modular design and intelligent operation processes, it provides reliable testing solutions for liquor production, quality control, and scientific research institutions. Based on gas chromatography technology, the instrument achieves rapid quantitative analysis of ethanol, methanol, and other volatile components through optimized injection, separation, and detection systems.
The technological advancements include three key aspects: Firstly, the high-sensitivity Flame Ionization Detector (FID) can accurately capture trace component signals with alcohol detection limit reaching 0.01% (v/v). Secondly, the dual-channel gas path control system combined with fully electronic pressure regulation modules maintains carrier gas flow stability with less than 0.5% deviation. Thirdly, the intelligent temperature control system implements multi-stage programmed heating, achieving complete separation of main components in alcoholic samples within 8 minutes.
Equipped with professional chromatography workstation software, the instrument features automatic peak integration, multi-component calibration, and intelligent report generation. Pre-installed method packages for baijiu, wine, beer and other specific sample types allow users to directly apply preset parameters. The optional automatic liquid sampler ensures precise injection volume control (0.1-2μL) with repeatability RSD below 1.2%.
Applications cover comprehensive testing of distilled spirits, fermented wines, and blended alcoholic beverages, particularly suitable for alcohol degree verification, impurity screening, and production process optimization. User-oriented designs include self-diagnostic functions, gas leakage alarms, and encrypted data storage, meeting laboratory safety management requirements. Constructed with industrial-grade stainless steel gas lines and components verified through 2,000-hour endurance testing, the instrument guarantees long-term operational stability for continuous analytical tasks.
