Description and Function
Principal Applications
• Drinking water
• Wastewater
• Groundwater
• Surface water

The Flow Solution® FS 3100 Automated Chemistry Analyzer is a modular system
for performing continuous ow analysis methods on water samples, soil, or plant
extracts and digests using FIA or SFA techniques. The FS 3100 consists of an X-Y-Z
autosampler (90 or 360 position), multi-channel precision pump, electrically-actuated
sample injection valve, VersaChem Multi-Test Manifold™, and Expanded Range™
photometric or amperometric detector.
The FS 3100 supports two channels for FIA methods and three channels for SFA
methods, minimizing the time involved in changing chemistries for different analytes.

• Industrial waste
• Soil extracts

Operating Principle

• Plant digests

The FS 3100 Automated Ion Analyzer supports and performs two continuous ow
analysis techniques: ow injection analysis (FIA) and segmented ow analysis (SFA).

Methods

In FIA methods, a highly reproducible sample volume is injected into a carrier stream,
followed by downstream reagent mixing under laminar ow conditions for a precise
residence time within an analytical cartridge. FIA chemistries produce sharp, transient,
and nearly-Gaussian peaks. Precise sample volumes and reaction times do not require
reaction completion for accurate measurements. Peak area is used for measurements.

In SFA methods, a sample volume is aspirated into a carrier stream and segmented with
air or an inert gas, followed by downstream reagent mixing under turbulent “bolus”
ow conditions. The segmentation gas decreases sample dispersion and inter-sample
mixing, allowing longer residence time within the analytical cartridge and enabling
reactions to reach equilibrium before detection. SFA chemistries produce at-topped
peaks, representing reaction completion or steady state. Peak height is used for
measurements.
