Product Composition
The instrument consists of three parts: liquid phase pump unit, docking unit (including UV digestion function) and atomic fluorescence host, which cooperate with the chromatography workstation unit to realize the complete analysis process:
- First, the sample enters the liquid phase pump unit, and the speciation and valence state of the elements are separated through the chromatographic column;
- The separated sample enters the docking unit, which is responsible for realizing the signal docking between the liquid phase pump and the atomic fluorescence host, and also digesting and converting the organic matter separated by the liquid phase into inorganic matter;
- The treated sample enters the atomic fluorescence host, is detected by hydrogenation reaction, and finally outputs accurate results.
Product Features
- Flexible pump configuration, optional single pump or binary gradient pump. The signal is automatically triggered during the injection process, and the workstation can automatically collect signals and record data in real time with high efficiency and convenient operation;
- Equipped with an independent liquid crystal display operation platform, the running status is intuitive and clear, and the operation mode of the liquid phase pump can be flexibly adjusted;
- Built-in filtration device can effectively protect the analytical column and extend its service life;
- Adopt the fusion connection technology of quartz capillary and PEEK tube, successfully eliminate dead volume, reduce peak broadening, and have excellent anti-ultraviolet, corrosion resistance and aging resistance performance;
- Digestion power and time can be flexibly adjusted, which greatly enhances the digestion capacity and adapts to different sample processing requirements;
- Adopt light leakage free cooling technology, which not only avoids the harm of ultraviolet light to human body, but also eliminates the peak broadening phenomenon caused by air resistance generated by heat, ensuring the accuracy of detection and operational safety;
- Equipped with multi-functional data interface, supporting analog signal & digital signal data output, compatible with a variety of chromatography workstations, and adapted to the equipment configuration requirements of different laboratories.
