Product classification: Syringe Pump Series
Product Overview
The AFS-97 Series Atomic Fluorescence Spectrophotometers, are high-performance instruments designed for ultra-trace element analysis. They are widely used for the detection of arsenic (As), mercury (Hg), selenium (Se), antimony (Sb), and other trace elements across environmental monitoring, food safety, quality inspection, geology, mining, and scientific research applications.
Key Features
-
High-sensitivity multi-element analysis
Enables ultra-trace detection of up to twelve elements, including arsenic, mercury, selenium, and antimony. -
Flexible multi-channel detection
- AFS-9710 / AFS-9750: simultaneous analysis of 2 elements
- AFS-9770: simultaneous analysis of 4 elements
- Significantly reduced analysis time per sample
-
High-throughput sample handling system
Ultra-quiet, high-speed polar coordinate autosampler supports multiple tray configurations:- 69 positions (25 mL)
- 134 positions (15 mL)
- 183 positions (10 mL)
-
Advanced fluid control technology
AFS-9750 features a 10-roller, 6-channel high-stability peristaltic pump system, ensuring consistent sample injection and minimising pulsation effects. -
Innovative valve design for higher reliability
Pinch valve technology replaces traditional check valves and multi-channel valves, preventing reagent contact with valve components, eliminating corrosion and memory effects, and delivering a service life of over 500,000 cycles. -
Hybrid pump technology
Combines syringe pump precision with peristaltic pump speed, enabling accurate injection, fast processing, and online system cleaning. -
Automated operation and calibration
Supports single-point calibration, automatic dilution, and fully automated measurement workflows. -
Enhanced measurement stability
Sample and current isolation technology reduces diffusion interference, improving analytical accuracy. -
Optimised atomisation system
Shielded quartz furnace low-temperature atomiser reduces fluorescence quenching and gas-phase interference, improving atomisation efficiency. -
Advanced gas–liquid separation system
Airtight two-stage separation design eliminates the need for liquid replenishment and waste discharge during operation. -
Smart instrument management
Automatic element recognition and intelligent monitoring of coded hollow cathode lamp lifespan. -
Efficient gas system design
Array-type gas circuit with advanced throttling technology significantly reduces argon consumption. -
