Improvement of Fluorescence Quantitative Analysis Experiment: Simultaneous Determination of Rhodamine 6G and Rhodamine 123 in Food Using Chemometrics-Assisted Three-Dimensional Fluorescence Method

The existing instrument analysis experiment, “Molecular fluorescence method for the determination of rhodamine B”, is overly simplistic and dose not account for real-world complexities. To address these issues, this improved experiment utilizes three-dimensional fluorescence scanning to acquire sample data. Instead of complex preprocessing steps, chemometric algorithms are applied to extract the pure signals of the target analytes, enabling the simultaneous determination of rhodamine 6G and rhodamine 123 in dyed chili. This improvement enhances students' ability to approach problems comprehensively and develop innovative solutions.
