Innovation Solution
A colorimetric process involving a reaction with [4-(dimethylamino)phenyl]methanol (p-DAB) or 4-Dimethylaminocinnamaldehyde (DMACA) and an acid is employed to create a colorimetric reading, using reference samples for comparison, to determine fludioxonil content in liquid media.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If colorimetric analysis is performed to determine fludioxonil content, then measurement capability is provided, but existing methods lack reliability and efficiency
Solution Approach 1:
The patent employs colorimetric analysis where fludioxonil reacts with p-DAB indicator in the presence of acid to produce a color change. The intensity of the color developed is proportional to the fludioxonil concentration, enabling quantitative measurement through colorimetric reading or visual comparison with reference samples of known concentrations.
Solution Approach 2:
The patent introduces p-DAB (4-(dimethylamino)phenyl]methanol) as an intermediary indicator substance that mediates the detection of fludioxonil. The indicator reacts specifically with fludioxonil in the presence of acid to produce a measurable color signal, serving as a reliable intermediary for quantification.
2Measurement precision
If colorimetric analysis is performed to determine fludioxonil content, then measurement capability is provided, but existing methods lack efficiency
Solution Approach 1:
The patent replaces complex mechanical or instrumental analytical systems with a simplified colorimetric system. Instead of using sophisticated equipment for fludioxonil detection, the method uses chemical reaction-based color development that can be measured with simple colorimeters or even visual comparison, significantly improving measurement efficiency and accessibility.
3Measurement precision
If reference samples are used for comparison, then measurement accuracy is improved, but process complexity increases
Solution Approach 1:
The patent creates reference samples that are copies or replicas of actual samples with known fludioxonil concentrations. These reference samples replicate the matrix and conditions of test samples, providing a basis for direct visual or instrumental comparison. This copying approach simplifies the measurement process by eliminating the need for complex calibration curves or standard addition methods.
