Chugai Technos Corporation

We perform trace analysis of environmental pollutants and hazardous substances, as well as measurement and analysis and environmental monitoring surveys based on various laws and regulations.In addition, our specialist engineers are available to provide consultation regarding the measurement and analysis of substances not regulated by analytical laws, such as soil, waste dust, and metals.

We handle everything from PCBs (polychlorinated biphenyls) in the environment to insulating oils for various heavy electrical equipment and graduation determination tests for PCB processing products.
Taking advantage of our track record in insulating oil analysis, we provide highly accurate data quickly using GC-ECD or HR-GC/MS. In addition, insulating oil collection containers will be shipped free of charge after a contract is signed.

We provide consultations regarding the analysis of drinking water, groundwater, etc. samples using test methods approved by the United States Environmental Protection Agency (US EPA). Drinking water testing that complies with US regulatory standards is carried out by our company and overseas cooperating analysis laboratories.
EPA Method 533 (drinking water) and EPA Method 537.1 (drinking water, environmental water, and wastewater), which are analytical methods for PFAS, which are attracting attention as an environmental issue, are performed in an environment that has been certified to ISO17025, an international standard for laboratory accreditation.

Understanding the properties and characteristics of biomass fuel is essential for facility design and operation management.

Biomass fuels contain a higher amount of alkali metals than coal, which causes problems such as poor flow due to the formation of sintered bodies and equipment corrosion due to Cl and S. For this reason, accurate understanding of the ash composition is essential for the operation and management of power generation facilities.
We can provide a wide range of services, from ashing preparation that meets various standards (JIS, ISO, etc.) and test conditions to quantitative metal analysis using ICP-OES.

In accordance with the above-mentioned legal amendments, our company has "specific or general building asbestos-containing building material inspectors" who carry out preliminary inspections. The analysis inspections are carried out by "instructors" and "skill test passers" certified by the Japan Environmental Measurement and Analysis Association, and analysts who have "A rank or passed" certification in the asbestos analysis technology evaluation business of the Japan Working Environment Measurement Association.
Regarding analysis methods, we support all of JIS A 1481-1 to -5, as well as ISO and US EPA methods.

In the analysis of airborne asbestos at demolition sites and in general environments, in addition to phase contrast microscopy, we can also widely handle phase contrast/polarized light microscopy, dispersion staining, electron microscopy, etc. We can also collect and analyze RCF (refractory ceramic fiber), which has been added to the list of specified chemical substances.

We perform comprehensive analysis of foreign matter contamination in products, adhesion to pipes, etc., and other unknown samples using the following equipment.

Organic-based foreign matter: Qualitative analysis of organic compounds is performed using FT-IR.
Inorganic foreign matter: The elemental composition ratio is analyzed using SEM-EDX, and if the inorganic compound form is required, it is analyzed using XRD.
If an investigation into an unknown substance is required, we will propose the investigation method.

We conduct physical property tests and heat release rate tests on wood pellet fuel to obtain parameters related to its heat generation characteristics. Through simulations, we estimate the critical temperature at which a large amount of wood pellets will ignite and the storage period.
