Background:

Chemiluminescence analysis is a sensitive technique for detecting various analytes.
Flow cells are crucial components in automated analytical systems, influencing performance metrics.
Existing flow cells like spiral and helix designs have limitations in sensitivity and detection limits.

Purpose of the Study:

To introduce and evaluate a new flow cell, termed the bundle cell, for chemiluminescence analysis.
To compare the performance of the bundle cell against conventional manual, automated batch, and other flow cell methods.
To determine key figures of merit for chromium(III) determination using the bundle cell.

Main Methods:

Development and implementation of a novel bundle flow cell for flow injection analysis.
Chemiluminescence detection based on catalyzed chromium(III) luminol oxidation by hydrogen peroxide.
Comparative analysis of the bundle cell with quartz, helix, and spiral flow cells, as well as batch methods.
Determination of figures of merit including limit of detection, sensitivity, accuracy, and precision.
Analysis of real water samples for chromium content.

Main Results:

The bundle cell demonstrated a significant improvement in sensitivity, approximately 50% higher than the spiral cell.
A lower limit of detection was achieved with the bundle cell compared to other tested flow cells.
Performance metrics (accuracy, precision) of the bundle cell were comparable to automated batch procedures.
Successful application of the bundle cell for chromium determination in real water samples.

Conclusions:

The bundle flow cell represents a significant advancement in chemiluminescence analysis, particularly for chromium(III) detection.
It offers superior sensitivity and detection limits over commonly used flow cells.
The bundle cell provides a viable and efficient alternative to batch methods for environmental water analysis.
