We provide consistent support from the analysis of minute stains on the sample surface to the investigation.
There can be various causes for stains that occur on the surface of the product, depending on the case. Our company will propose the most suitable analysis method according to the condition of the stain. We will consistently address the issue, not only by identifying the causative substances of the stain through component analysis but also by investigating the extent of the spread through appearance photography.

basic information
●Analysis of Various Stains There are various patterns in the causes of abnormal occurrences resembling stains. Our company is capable of identifying the causative substances, regardless of whether they are organic, inorganic, or compounds. Additionally, if abnormalities in surface properties are observed due to stains, we clarify the details of the abnormal areas through surface observation and shape measurement (investigation of uneven shapes, etc.). ●Investigation of Stain Spread By using mapping analysis, we can investigate the extent of stain spread. By coloring elements based on their concentration, it is possible to visually grasp the condition of the sample. ●Analysis of Thin Stains We can also analyze very thin stains, such as oxide films, on the nanometer scale. By using ESCA/XPS, we can conduct analysis from the surface down to the nanometer level. Furthermore, depth analysis is also possible through ion sputtering.

Applications/Examples of results
●Identification of the substances causing stains on metals We offer services for identifying the substances causing abnormal stains on the surfaces of inorganic materials, including metals, through observation and component analysis, as well as analyzing the causes of their occurrence. Analysis can be performed not only from the surface but also from cross-sectional samples. ●Component analysis and extent confirmation of organic stains For organic samples such as fabrics, paper, and resins with stain-like foreign substances, we provide surface analysis using FT-IR (Fourier-transform infrared spectroscopy) and analysis by extracting components for GC-MS (gas chromatography-mass spectrometry).
Company information
Our main business is providing technical services to evaluate the reliability of developed products. We not only provide evaluation data in accordance with standards and regulations, but also propose optimal methods, conditions, and equipment for evaluation purposes, as well as design and manufacture original equipment and jigs for non-standard evaluations. Additionally, we handle three evaluation techniques—measurement, testing, and analysis—comprehensively, allowing us to offer complex services that span diverse equipment and suggest more multifaceted evaluation methods.
