Mercury Arsenic Elemental Analyzers, Atomic Fluorescence Spectrometer AF402


The Atomic Fluorescence Spectroscopy (AFS) technique is widely used for determination of hydride forming elements and Mercury analysis. The technique provides an alternative to the conventional method of connecting a hydride generator to an Atomic Absorption Spectrophotometer (AAS). Due to the high intensity Hollow Cathode lamp source and low baseline noise offered by this technique, the usable sensitivity is greatly improved offering very low detection limits (ppt).

The AFS instrument fulfils the analysis by means of simultaneous detection, accurate sample introduction and stable furnace temperature control complementing the more widely used AAS flame/graphite systems.


Standard Features

Light Source

  • High intensity Hollow Cathode lamps for greater intensity and stability
  • Up to three lamps can be installed for simultaneous analysis
  • All lamps are uniquely data coded offering important information to the PF Win operating software
  • Optical System
  • Shielded optical design greatly reduces light interference
  • Enhanced signal to noise ratio for increased analytical sensitivity
  • Unique optical configuration for increased fluorescence intensity. Up to twice the fluorescence intensity found in traditional AFS systems.
  • High Quantum Solar Blind Photomultiplier Tube fitted as standard to ensure optimum stability

Atomiser System

  • High precision quartz atomizer tube designed for optimum performance, durability and long life
  • Self-igniting Argon/Hydrogen flame with software controlled heater coil
  • Adjustable height control for improved optimization
  • Integrated fume exhaust system to decontaminate pollution

Hydride Generator

  • Built in hydride generator with continuous flow
  • Multi-pump with individual pressure adjustment for uptake control of reagents and carrier liquids
  • Introduction of sample using motorized syringe drive and unique three way control valve. Software controlled for greater accuracy
  • High efficiency glass liquid separator which optimizes the separation minimizing pressure fluctuations and improving measurement precision
  • Reagent compartment stores reagents safely and cleanly. Storage for up to four containers
  • Low level reagent monitoring


Autosampler


  • Integrated autosampler
  • XYZ configuration
  • x 45 vial trays for automated sample introduction
  • Auto dilution using motorized syringe drive and selection valve
  • Full calibration using only one stock standard solution
  • Fully controlled by the PF Win software
  • Electronic Control System
  • High technology electronics and PCB components
  • Rear mounted and separated electronic section to eliminate carry over from hydride technique
  • PF Win instrument control software
