A novel approach to non-segmented flow analysis. Part 2. A prototype high-performance analyser.

Area of Science:

• Analytical Chemistry
• Environmental Science
• Instrumentation

Background:

• Continuous flow analysis (CFA) is a vital technique in analytical chemistry.
• Existing CFA methods can be complex and require significant reagent volumes.
• There is a need for high-performance, automated analytical systems.

Purpose of the Study:

• To describe a novel high-performance continuous flow analyser.
• To evaluate the analyser's performance using standard and real-world samples.
• To compare the new system with a traditional segmented continuous flow method.

Main Methods:

• Development of a continuous flow analyser driven by gas pressure.
• Computer-controlled solenoid valves for precise carrier and reagent delivery.
• Application of the analyser for chromium (VI) determination.
• Testing with ammonium ion analysis in potable and effluent water samples.

Main Results:

• The analyser demonstrated high performance in determining chromium (VI).
• Ammonium ion analysis in real water samples yielded comparable results to a segmented continuous flow method.
• The system proved effective for both standard and complex sample matrices.

Conclusions:

• The gas pressure-driven continuous flow analyser offers a high-performance alternative.
• The automated system provides accurate and reliable results for water quality analysis.
• This technology has potential for various environmental and industrial monitoring applications.
