Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The analysis of isotope ratios in complex molecules is hindered by isotope fractionation risks and high preparative efforts, as substances are often not present in the desired form, requiring separation techniques that are inefficient and labor-intensive.
Innovation Solution
The method involves subjecting a liquid phase to electrolysis, either through oxidation and/or reduction, to produce the desired substance or a pre-product, which can be separated and directly analyzed, using an electrolysis device with specific electrode and channel designs to enhance conversion efficiency and minimize isotope fractionation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separation techniques are used to isolate substances from complex compounds, then the substances can be analyzed, but isotope fractionation occurs and preparative effort increases
Solution Approach 1:
The invention changes the chemical state of the substance through electrolysis, converting complex molecules into simpler gaseous forms (CO2, N2, H2, etc.) directly in the liquid phase. This parameter change from complex molecular structure to simple gaseous state enables direct analysis without separation techniques that would cause isotope fractionation.
Solution Approach 2:
The invention extracts the analyte substance from complex compounds through in-situ electrolysis within the liquid phase, converting it directly into a measurable gaseous form. This extraction occurs during the electrolysis process itself rather than through separate purification steps, avoiding isotope fractionation.
2Measurement precision
If separation techniques are used to isolate substances from complex compounds, then the substances can be analyzed, but preparative effort becomes disproportionately high
Solution Approach 1:
The invention merges the sample preparation step with the analysis step by performing electrolysis directly in the liquid phase containing the complex compounds. The conversion of complex molecules to measurable gases occurs within the same system used for analysis, eliminating separate preparative steps and enabling high throughput.
Solution Approach 2:
The invention enables continuous analysis by performing electrolysis on flowing liquid phases or in continuously operated cells. The conversion of complex compounds to measurable gases occurs continuously without interruption for sample preparation, maximizing analytical productivity.
3Productivity
If complex compounds are analyzed directly, then preparative effort is reduced, but substances are not in the desired form for analysis
Solution Approach 1:
The invention changes the physical and chemical parameters of the analyte through electrolysis, converting complex non-gaseous molecules into simple gaseous forms (CO2, N2, H2). This parameter change from complex liquid/solid state to simple gaseous state makes the substances directly detectable by standard analytical instruments without requiring preparative conversion.
