Solution Overview
Problem
Existing analyte concentrator systems face challenges with analyte molecules and contaminants in wash and eluent fluids, leading to inaccurate analytical results due to background noise, especially when dealing with trace amounts of analytes, as these fluids may contain the analyte of interest and ionic contaminants.
Innovation Solution
The system connects the effluent outlet of an analyte concentrator to an eluent generation module, utilizing the substantially analyte-free effluent to produce a substantially analyte-free eluent, thereby minimizing background signal during analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional eluent and wash fluids are used in analyte concentrator systems, then the system can operate with standard fluid sources, but analyte molecules and ionic contaminants in these fluids cause background noise that overwhelms trace analyte signals
Solution Approach 1:
The patent extracts and removes analyte molecules from the eluent and wash fluids through pre-treatment steps such as filtration, adsorption, or chromatography. This extraction process eliminates the harmful background analyte signal while preserving the essential fluid properties needed for concentrator operation, thereby improving measurement precision without sacrificing system functionality.
Solution Approach 2:
The patent introduces intermediary substances or devices between the standard fluid sources and the analyte concentrator. These intermediaries (such as guard columns, adsorbent materials, or selective membranes) capture and retain analyte molecules from the eluent and wash fluids, preventing them from reaching the concentrator and creating background noise, thus resolving the contradiction between using standard fluids and avoiding contamination.
2Ease of operation
If standard water sources are used to generate eluent and wash fluid, then the system is simple to operate, but ionic contaminants in the water interfere with analyte measurement
Solution Approach 1:
The patent implements self-service mechanisms where the system automatically treats the water source to remove ionic contaminants. This is achieved through integrated filtration systems, ion-exchange resins, or reverse osmosis units that continuously purify the water supply without requiring manual intervention, thereby maintaining ease of operation while eliminating ionic contaminant interference.
Solution Approach 2:
The patent changes the physical or chemical parameters of the water source by adjusting pH, ionic strength, or purity levels through treatment processes. By modifying these parameters, the system converts ordinary water into a contaminant-free eluent and wash fluid suitable for trace analyte analysis, resolving the contradiction between operational simplicity and contaminant removal.
3Productivity
If eluent and wash fluid volumes are increased to ensure adequate flow through the concentrator, then proper washing and elution are achieved, but the concentration of analyte in the final sample is reduced
Solution Approach 1:
The patent applies preliminary action by pre-concentrating the analyte in the concentrator column before elution. The concentrator is conditioned and prepared in advance to maximize analyte retention, allowing for efficient washing with larger volumes without losing the analyte. During elution, a small volume of strong eluent is used to release the pre-concentrated analyte, thereby achieving both high washing efficiency and high final concentration.
Solution Approach 2:
The patent employs periodic action through cyclic operation modes that alternate between concentration, washing, and elution phases. During the concentration phase, analyte is accumulated; during washing phases, large volumes of fluid are used to remove contaminants; and during elution, a small volume restores the analyte to solution. This periodic cycling resolves the contradiction by separating the volume requirements of washing from the concentration requirements of the final eluate.

Function Achieved in This Case
This approach ensures accurate, quantitative measurement of analytes by eliminating or minimizing analyte and contaminant interference, even at trace concentrations, by generating an eluent that is free from the analyte of interest, thus enhancing the reliability of analytical results.

AI summary
Systems and methods for concentrating an analyte preparatory to analysis thereof include processing the effluent of an analyte concentrator to produce an eluent for eluting an analyte retained in the same or separate concentrator, and systems implementing the same. The analyte concentrator system connects the effluent outlet of an analyte concentrator column to an eluent generation module such that the substantially analyte-free effluent discharged from the analyte concentrator column passes fluidly into the eluent generation module. Eluent generated from the substantially analyte-free effluent in the eluent generation module is likewise substantially free of the analyte. The systems and methods can minimize and/or (substantially) eliminate background signal during analysis of the concentrated analyte.
