Engineering Contradiction Analysis
1Adaptability or versatility
If a linear function is used to approximate the relationship between mobility Rf and solvent mixing ratio (B/A), then the prediction of liquid chromatography results becomes feasible, but the prediction accuracy is insufficient for wide range of compounds
Solution Approach 1:
The invention changes the mathematical parameters of the prediction model from a simple linear function to a more sophisticated equation incorporating multiple variables (Rf value, solvent mixing ratio B, and interaction term a1×B). This parameter enhancement allows the model to accurately predict chromatography results across a wide range of compounds while maintaining computational feasibility
Solution Approach 2:
The invention introduces an intermediary calculation step where the support device computes prediction values using the enhanced equation before comparing them with actual chromatography results. This intermediary processing layer bridges the gap between simple TLC measurements and accurate LC predictions, enabling both wide applicability and high precision
2Productivity
If thin-layer chromatography is used to predict liquid chromatography results, then experimental efficiency is improved, but the prediction accuracy for separation conditions is insufficient
Solution Approach 1:
The invention replaces the purely empirical mechanical approach of TLC with a mathematically enhanced prediction system. By substituting simple visual TLC interpretation with computer-based calculation using the enhanced equation, the system maintains the efficiency of TLC while achieving LC-level prediction accuracy
Solution Approach 2:
The invention implements a feedback mechanism where the support device compares predicted values (calculated from TLC data using the enhanced equation) with actual chromatography results. This feedback loop allows continuous refinement and validation, ensuring both high efficiency and accuracy in predicting separation conditions
