Intended Use：
- Solvent Residue Analysis: Specifically designed for detecting solvent residues in packaging and printed materials.
- Purity & Content Testing: Used for assessing the purity and quantitative content of various industrial solvents.
- Detectable Substances: Benzene, Cyclohexanone, Xylene, Ethanol, Ethylbenzene, Isopropanol, Propanol, Butanol, Ethyl Acetate, Isopropyl Acetate, n-Butanol, Toluene, n-Butyl Acetate, Aniline, 4-Methyl-2-Pentanone (MIBK), etc.
Operating Principle：
The Gas Chromatograph (GC) utilizes an inert gas as the mobile phase and employs column separation technology. As the analyte mixture enters the chromatographic column, individual components move at different rates due to their varying distribution coefficients within the column. Once separated, the components sequentially enter the detector, where they are converted into electrical signals and sent to a data workstation for comprehensive qualitative and quantitative analysis.
Product Features：
- Smart Interaction: Features a 7-inch color touchscreen with a next-generation smart OS, providing a smartphone-like intuitive interface and clear logic.
- Expandable Detectors: Can be equipped with multiple common detectors simultaneously. Fully compatible with chromatographic workstations for intuitive result visualization.
- High-Efficiency Cooling: Large-capacity column oven features an automatic rear-door mechanism for rapid cooling.
- Versatile Injection Modes: Configurable for Packed/Capillary column injectors, Headspace autosamplers, Thermal Desorption (TD), Pyrolysis (Py), etc.
- Safety & Diagnostics: Includes self-diagnostic capabilities and over-temperature protection, which automatically halts heating and triggers an alarm if thresholds are exceeded.
- Ultra-Quiet Operation: Features an advanced noise suppression system that eliminates fan noise during operation.
- Flexible Architecture: Versatile injector port design and a spacious oven facilitate complex analysis tasks using various columns, broadening the scope of testable samples.
- Precision Control: Microcomputer-controlled with a temperature stability accuracy of .
- Dual Overheat Protection: Features hardware circuit and software program redundancy for maximum safety.
