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 improved sensitivity and stability.
  • Pre-aligned lamp assemblies for trouble free installation.
  • All lamps are uniquely data coded offering important information to the PF Win operating software.
  • l Up to 3 lamps can be installed for simultaneous analysis.

Optical System

  • Double beam optical system to eliminate drift from the light source and the detector.
  • Shielded optical design greatly reducing light interference.
  • Enhanced signal to noise ratio for increased analytical sensitivity.
  • Unique optical configuration for increased Fluorescence intensity. Up to twice the intensity found in traditional AFS systems.
  • High Quantum Solar Blind detector fitted as standard toensure optimum stability.

 

Atomiser System

  • High precision quartz tube designed for optimum performance, durability and long life.
  • Adjustable height control for improved optimisation.
  • Integrated 2 stage, fully sealed, fume exhaust system to decontaminate toxic elements and pollution.
  • Gold Mesh fitted to the chimney removes any mercury pollutant.

Hydride Generator

  • Integrated continuous flow Hydride System.
  • Gas pressure sampling offers maintenance free operation.
  • Online auto dilution and multiple auto purge by gas driven sequential injection system.
  • Fully sealed reservoir bottles for extended solution life.
  • New design Gas Liquid Separator with magnetic stirring for improved repeatability of analytical results.
  • Liquid Separator cooled directly by specially designed Peltier system to remove unwanted water in the formed hydride and greatly reduce Fluorescence quenching thus increasing the sensitivity.
  • Unique high volume reagent storage positioned outside of the instrument to reduce contamination.
  • Connection of carrier and reducer liquids to instrument using long life chemical resistant FEP tubing.

Electronic Control

  • High technology electronics and PCB components.
  • PF Win 3.0 software offers full control of AF420 instrument and accessories.
  • Windows operating software
  • New features include: QC functions, online data sharing, self diagnostics, result and resource management.
  • Full GLP version available for multiuser group management and log.
