AIMsight – Applications
Electrical and Electronic
Shown here is an example of analyzing a foreign matter adhering to the surface of a button battery. By using the wide-ﬁeld camera, it is possible to observe entire components and determine measurement points quickly. We performed the analysis using the direct ATR measurement method.
A search of the obtained data using the Shimadzu Original Contaminant Library revealed that the foreign matter consisted mainly of acrylonitrile butadiene rubber (NBR) and contained CaCO3, aluminum silicate (KAOLIN), and phthalates as additives.
Before the measurement, the length of the foreign matter was measured using the length measurement function. As a result, we found that the foreign matter adhering to the button battery surface was 18 μm on the short side and 60 μm on the long side.
Machinery and Transportation
This is an example of analyzing resin parts exposed to sunlight for long period. By measuring the infrared spectrum of the component cross-section, the progress degree of the degradation about depth direction from the surface can be visualized.
Pharmaceutical and Life Science
This is an example of the analysis of foreign matter adhering to the surface of a pharmaceutical tablet. By being taken to a diamond cell and rolled, transmission measurement can be performed on various shaped samples.
Shown here is an analysis example of microplastics collected on polytetrafluoroethylene (PTFE) filter paper.
Micro-transmission mapping analysis was performed to determine the material of the microplastics using Shimadzu's original UV-damaged plastic library.
The results showed that the microplastics were polyethylene (PE) and polypropylene (PP). The absorption around 1,200 cm -1 is due to PTFE, the material used for filter paper.
In addition, we performed a mapping analysis of microplastics on filter paper.
For the mapping data, we created chemical images based on the corrected height of the CH2 rolling vibration mode of PE (718 cm-1) and the CH3 symmetric deflection mode of PP (1,373 cm-1).
