Giới thiệu các đặc tính của thiết bị
Fully automated operation with computer-controlled functions ensures reliability and safety. A 12-rotor peristaltic pump and mass flow controllers (MFC) maintain stable sample introduction. Self-developed all-solid-state RF power and intelligent matching technology enhance stability and efficiency. The high-efficiency optical system (echelle grating-prism cross dispersion) combined with a large CID detector delivers ultra-low stray light, high resolution (<0.0068nm), and wide dynamic range (10⁸), achieving detection limits as low as 1ppb. Non-destructive readout and ultra-fast testing (2ms per spectral line) meet diverse needs. Advanced software supports intelligent algorithms and offline reprocessing, ideal for precise analysis in metallurgy, geology, environmental monitoring, pharmaceuticals, and more.
The instrument features fully automated operation, with all functions (except the power switch) controlled by a computer, ensuring reliability, safety, and user-friendly operation. Equipped with a 12-rotor peristaltic pump, its speed can be precisely adjusted based on flow requirements, achieving synchronized sample introduction and waste removal for enhanced system stability. Gas flow is automatically regulated via mass flow controllers (MFCs), ensuring continuous adjustment and stable output of carrier gas, plasma gas, and auxiliary gas, thereby solidifying the stability of both the light source and sampling system. The self-developed all-solid-state RF power supply is compact, efficient, and delivers stable power output with integrated multi-protection functions, significantly improving instrument safety and reliability. Rapid auto-matching technology intelligently optimizes power transmission to the load, simplifying ignition procedures and enhancing power efficiency.
The modular sampling system supports various nebulizers (e.g., high-salt and HF-resistant models) and auto-samplers, catering to diverse detection needs. The precision optical system utilizes echelle grating-prism cross dispersion to maximize light throughput while achieving high resolution (<0.0068nm@200nm). Combined with ultra-low stray light design, it effectively reduces background interference, particularly enabling accurate detection of deep-UV elements (e.g., P, S, As). The large CID detector (27.6mm×27.6mm target) employs non-destructive readout (NDRO), offering superior signal-to-noise ratio compared to CCD. Its wide dynamic range (10⁸) and anti-blooming capability allow simultaneous analysis of strong and weak spectral lines. An intelligent wavelength calibration algorithm eliminates the need for additional standard solutions, saving time while ensuring accuracy. With ultra-fast testing capabilities, single-line readout takes ≤2ms, and full-element analysis can be completed within 1 minute.
The advanced software supports qualitative, semi-quantitative, and quantitative analysis, integrating AI-driven background correction, interference removal algorithms, and offline reprocessing. Its intuitive interface ensures efficient operation, making it ideal for complex sample analysis in geology, environmental monitoring, pharmaceuticals, and more.
