AF420

Product catalog summary

Overview: The AF420 Atomic Fluorescence Spectrometer is designed for elemental analysis across various industries such as agriculture, public health, pharmaceuticals, metallurgy, food and beverage, clinical, geological, and petrochemical sectors.

Light Source: The instrument uses high-intensity hollow cathode lamps for enhanced sensitivity and stability. It supports up to three lamps for simultaneous analysis, with pre-aligned assemblies for easy installation.

Optical System: Features a double beam optical system to minimize drift and interference, enhancing signal-to-noise ratio and fluorescence intensity. It includes a high quantum solar blind detector for optimal stability.

Atomiser System: Utilizes a high-precision quartz tube with adjustable height control and a two-stage fume exhaust system to manage toxic elements. A gold mesh in the chimney helps remove mercury pollutants.

Hydride Generator: The integrated continuous flow system offers maintenance-free operation with online auto dilution and multiple auto purge capabilities. It includes a gas-liquid separator cooled by a Peltier system to improve sensitivity.

Electronic Control: The AF420 is controlled by PF Win 3.0 software, offering features like QC functions, online data sharing, and self-diagnostics. It supports multiuser management and logging.

Detection Limits: The spectrometer provides low detection limits for elements such as Arsenic, Bismuth, Cadmium, and others, with RSD percentages under 1%.

Auto Sampler: Features an X, Y, Z drive configuration, controlled by PFWin software, with improved probe wash and large volume standard stock solution capabilities.

Speciation Analyser: Includes a built-in HPLC pump for high separation performance, capable of detecting and separating inorganic and organic compounds in under 12 minutes.

Specifications: The AF420 requires high purity Argon gas and features a quartz furnace tube with auto ignition. It supports USB and RS232 interfaces and operates on PFWin software. The instrument has a net weight of 35Kg and dimensions of 60cm x 57cm x 45cm.
