AF400

Simultaneous Atomic
Fluorescence Spectrometer

Features
Integrated Exhaust System
The configuration of exhaust system effectively
decontaminates exterior pollution ultimately enhancing
the accuracy of the measurements. The shielded optic
design greatly reduces light interference and enhances the
signal-noise ratio, increasing the sensitivity and precision
of the measurement.

Hollow Cathode Lamps
High intensity hollow cathode lamps provide increased
intensity and stability. The AF400 multi-channel
technology allows lamp configuration to be changed to
accommodate application specific requirements allowing
either simultaneous analysis increasing efficiency of
measurements or ultra high sensitivity.

Optical Design
The AF400 utilises a unique optical configuration that
increases fluorescence intensity and improves detection
limit. This arrangement allows approximately twice the
fluorescence intensity commonly found in traditional AFS
systems.

Quartz Atomiser
The quart atomiser is selected for durability and long life
operation.

Detection
The integration of high quantum solar photomultiplier
tubes ensures stability.
Gas/Liquid Separator
The high efficiency gas/liquid separator of hydride and
Hg cold vapour minimising pressure fluctuations and
improving measurement precision.

Sample Introduction
An integral high performance XYZ auto sampler with
2×45 vial trays provides automatic sample introduction
and dilution with superior repeatability. The efficient
operation maximises throughput and provides consistent
results.
Reagent Compartment
An integral drawer contains up to three reagent bottles
with low level indicators.
