Dual-Channel Atomic Fluorescence Spectrometer

Dual-channel atomic fluorescence spectrometers are widely used for trace and ultra-trace analysis of 11 elements including mercury (Hg), arsenic (As), antimony (Sb), bismuth (Bi), selenium (Se), tellurium (Te), cadmium (Cd), germanium (Ge), lead (Pb), tin (Sn), and zinc (Zn). It features a compact design, stable performance, and simple operation.

Dual-channel atomic fluorescence spectrometers are widely applied for testing the ultra-trace element content of these 11 elements in samples, with a minimum detection limit reaching the parts-per-trillion (ppt) level. Applications include environmental testing of water, soil, and air; food inspection; inspection and quarantine; pharmaceutical testing; cosmetic testing; soil, feed, and fertilizer analysis; geological and mineral testing; metallurgical sample testing; and educational research.

• High-Precision Gas Flow Control System
  The instrument employs a high-precision mass flow controller for gas flow regulation, achieving accuracy within 1 ml/min. It also features anomaly protection, automatically shutting off the gas supply when the instrument is inactive to conserve gas consumption.

• Intelligent High-Performance Hollow Cathode Lamp
  The instrument is equipped with an intelligent high-performance hollow cathode lamp. It automatically identifies the lamp element type and factory serial number, records the light source working life, and provides optimal operating conditions for the instrument.

• High-Precision Peristaltic Pump Injection System
  Utilizes a high-precision dual peristaltic pump intermittent flow injection system, ensuring injection accuracy and repeatability. It features simple operation, low failure rate, and extended service life.

• Online Dilution Method for Standard Curve Generation
  Generating standard curves requires only a single standard solution at the highest concentration point. The instrument automatically dilutes high-concentration samples and cleans the tubing, saving time and reducing costs associated with standard sample preparation.

• Real-time flame observation
  The instrument employs a real-time video flame monitoring system for intelligent flame surveillance during operation. Users can observe flame status in real time during testing, reducing the chance of external interference and enhancing user convenience.

• Dual-Source Front-End Design
  Enables simultaneous analysis of two elements with single-channel enhancement, significantly boosting element sensitivity and lowering detection limits. Light source replacement is quick and convenient.

• User-Friendly Intelligent Software
  Features a bilingual (Chinese/English) interface, fully automated qualitative and quantitative analysis, and program-based automatic testing. Operators switch samples based on instrument beep prompts. Upon completion, the system automatically calculates sample content and generates test reports.
