Digital image-based flame emission spectrometry.

Area of Science:

• Analytical Chemistry
• Spectroscopy
• Chemical Analysis

Background:

• Traditional flame emission spectrometry (trad-FES) is a widely used technique for quantitative chemical analysis.
• Existing methods may have limitations in sensitivity, precision, and detection limits.

Purpose of the Study:

• To introduce and validate a novel digital image-based flame emission spectrometric (DIB-FES) method for quantitative chemical analysis.
• To compare the performance of DIB-FES with traditional FES.

Main Methods:

• Development of a DIB-FES method utilizing a webcam to capture flame emission images.
• Creation of a novel mathematical model based on the RGB color system to process image data.
• Determination of lithium, sodium, and calcium concentrations in various samples using DIB-FES.

Main Results:

• A linear relationship was established between analyte concentration and the RGB-based analytical response.
• DIB-FES demonstrated comparable results to trad-FES, with no statistically significant differences observed.
• The DIB-FES method exhibited enhanced sensitivity, precision, and lower limits of detection and quantification.

Conclusions:

• The proposed DIB-FES method is a feasible and effective approach for quantitative chemical analysis.
• DIB-FES offers significant advantages over traditional FES, including improved analytical performance.
• The trivariate nature of webcam detection contributes to the enhanced characteristics of the DIB-FES method.
