Universal Sample Holder for XRF and FTIR Spectrometry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of mounting samples for analysis using both X-ray fluorescence spectrometers and Fourier transform infrared spectrometers complicates the user's job, especially when dealing with small samples, as they require different handling methods, increasing the risk of sample loss and user burden.
Innovation Solution
A sample holder with a pair of films that can be used for both spectrometers, where the sample is sandwiched between the films for X-ray analysis and not for infrared analysis, allowing for simplified mounting by maintaining the sample within the holder for both types of spectrometers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a user mounts a sample directly to a Fourier transform infrared spectrometer, then the analysis of organic substances can be conducted, but the user's job becomes complicated when also needing to analyze inorganic substances with an X-ray fluorescence spectrometer
Solution Approach 1:
The sample holder is designed to be universally compatible with both Fourier transform infrared spectrometers and X-ray fluorescence spectrometers. The holder body with sample receiving portion can accommodate samples for both types of analysis, and the optional films can be added or removed based on the specific spectrometer being used, eliminating the need for separate mounting procedures for different instrument types
Solution Approach 2:
The sample holder is divided into functional segments: a base holder body that provides universal compatibility, and optional films that can be independently added or removed. This segmentation allows the user to configure the holder for different spectrometer types by simply adding or removing the appropriate film, simplifying the mounting process while maintaining versatility
2Adaptability or versatility
If a user transfers a small sample between containers for different spectrometers, then both organic and inorganic analysis can be performed, but the risk of sample loss increases
Solution Approach 1:
The sample holder serves as a universal container that can be used with both Fourier transform infrared spectrometers and X-ray fluorescence spectrometers. The sample remains in the same holder body throughout both analysis types, eliminating transfer operations and the associated risk of sample loss while maintaining compatibility with multiple instrument types
3Adaptability or versatility
If films are added to the sample holder for X-ray analysis, then inorganic substance analysis can be conducted, but the holder structure becomes more complex
Solution Approach 1:
The film component is designed as a separate, removable segment from the holder body. This segmentation allows the film to be added only when X-ray fluorescence analysis is needed, keeping the basic holder structure simple for routine infrared analysis while providing the necessary complexity for X-ray analysis when required
Solution Approach 2:
The sample holder configuration is made dynamic through the ability to add or remove films based on the analysis requirements. The holder transitions between a simple state (holder body only for infrared analysis) and a more complex state (holder body with films for X-ray analysis), optimizing the structure for each specific application

Function Achieved in This Case
This solution simplifies the sample mounting process, reduces the risk of sample loss, and improves analysis accuracy by allowing the user to handle the sample holder as a single unit for both spectrometers, enhancing operational efficiency.
Implementation Method 1
During an analysis of the sample with the X-ray fluorescence spectrometer, the sample is irradiated with X-rays through one of the pair of films
Implementation Method 2
The other of the pair of films may be provided with an adhesive layer on a surface facing the one of the pair of films in a state where the sample is sandwiched between the pair of films
Implementation Method 3
The sample excited by excited X-rays emits fluorescence X-rays
Implementation Method 4
The Fourier transform infrared spectrometer irradiates the sample with infrared light and detects reflection light from the sample

AI summary
When conducting an analysis of a sample using an X-ray fluorescence spectrometer, a user allows a sample holder to hold the sample such that the sample is sandwiched between a first film and a second film, and mounts the sample holder in this state to the spectrometer. When conducting an analysis of the sample using a Fourier transform infrared spectrometer, the user allows the sample holder to hold the sample such that the sample is not sandwiched between the first film and the second film, and mounts the sample holder in this state to the spectrometer.
