Classification: Peristaltic Pump Series
Product Overview
The AFS-8900 Automatic Dual-Channel Hydride Generation Atomic Fluorescence Spectrophotometer, independently developed by Haiguang, is designed for high-sensitivity trace element analysis. It enables accurate detection of arsenic, mercury, selenium, antimony, and other trace elements across environmental monitoring, food safety, quality inspection, geology, mining, and scientific research applications.
Key Features
- Suitable for trace analysis of up to twelve elements including As, Hg, Se, and Sb
- Real-time drift correction for improved measurement stability
- Dual-channel design enables automatic two-element analysis with testing time under 30 seconds per sample
- Integrated intermittent-flow hydride generation system combined with main unit for compact, efficient operation
- Alternating sample and carrier introduction enables online cleaning, reduces cross-contamination, minimises reagent consumption, and eliminates waste discharge via mechanical power
- Sample/carrier isolation technology effectively eliminates diffusion effects for improved accuracy
- Supports single-point calibration, automatic dilution, and fully automated measurement
- Intelligent hollow cathode lamp system with automatic identification and lifespan monitoring
- Dual-mode lamp driving system (constant current and pulse power) for enhanced stability
- Low-temperature shielded quartz furnace atomizer reduces fluorescence quenching and gas-phase interference, improving atomisation efficiency
- Sealed two-stage gas-liquid separation system with no liquid addition or waste discharge required
- Optimised gas circuit with array structure and precision throttle control for reduced argon consumption
- Built-in self-check, automatic diagnostics, and fault alarm functions for reliable operation
- Argon-hydrogen flame observation window for real-time monitoring
- Highly integrated circuit design with separated high- and low-voltage modules for system stability
- Software compatible with Windows XP/7/8/10, featuring expert online assistance
- Data export to Excel for efficient analysis and network sharing
- Reserved speciation analysis interfaces for future functional expansion
