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 t
