![[Analysis Case] Qualitative Analysis of Organic EL Layer](https://image.mono.ipros.com/public/product/image/ce1/2000244258/IPROS8599875849827258305.jpg?w=280&h=280)
Suppression of component alteration through measurement surface finishing under atmosphere control.
We conducted qualitative analysis of the components by measuring the surface under controlled conditions, minimizing alterations due to processing, on a commercially available digital audio player equipped with an organic EL display.

By combining techniques, it is possible to obtain multiple types of component information.
In the analysis of foreign substances, it is important to appropriately select the analytical methods based on the size of the foreign substance, the expected materials, and the condition of the substrate. By combining techniques such as optical microscopy, elemental analysis (XRF), and bonding state analysis (XRD, FT-IR), it is possible to gain insights into the multiple components contained in the powder. This document presents examples of qualitative analysis of powder foreign substances using the aforementioned methods.
