AFS200T Series Dual-Channel Atomic Fluorescence Spectrometer

Product Overview
The AFS200T Series Atomic Fluorescence Spectrometer is a compact dual-channel analytical instrument designed for trace and ultra-trace determination of 11 elements, including arsenic (As), mercury (Hg), antimony (Sb), bismuth (Bi), selenium (Se), tellurium (Te), cadmium (Cd), germanium (Ge), lead (Pb), tin (Sn), and zinc (Zn).
The AFS200T uses a dual peristaltic-pump intermittent-flow injection system, non-dispersive optics, automatic gas-flow control, and a shielded quartz atomizer. Its dual-channel configuration enables simultaneous analysis of two elements, while single-channel enhancement can improve sensitivity and detection performance. The instrument is suitable for routine laboratory analysis where stable operation, simple handling, and low detection limits are required.

Key Features
• Dual-channel design for simultaneous analysis of two elements, with enhanced single-channel operation.
• Dual peristaltic-pump intermittent-flow injection system provides stable sample introduction and convenient maintenance.
• Non-dispersive optical system delivers high sensitivity in a compact instrument configuration.
• Automatic gas-flow control with dual mass flow controllers provides fast and stable flow regulation with control accuracy up to 1 mL/min.
• Real-time flame observation eliminates the need for a conventional flame observation window and allows continuous monitoring during analysis.
• Intelligent high-performance hollow cathode lamps automatically identify lamp information and record operating life and working conditions.
• Shielded quartz atomizer and two-stage gas-liquid separation help reduce fluorescence quenching and the influence of water vapor.

Working Principle
The AFS200T determines trace elements by atomic fluorescence spectrometry. The sample is introduced into the reaction system through the intermittent-flow injection system, where the target element is converted into volatile species through appropriate chemical reactions. The generated species are transported into the quartz atomizer and converted into free atoms.
The hollow cathode lamp provides element-specific excitation radiation. When the ground-state atoms absorb the characteristic radiation, they are excited to higher energy levels and subsequently emit characteristic fluorescence. The fluorescence intensity is measured by the optical system and correlated with the concentration of the target element.
The instrument supports automated qualitative and quantitative analysis, standard curve generation, sample calculation, pipeline cleaning, and test report generation through its dedicated software workstation.
