VOC and Stinking Substances Analysis

Volatile Organic Compounds (VOCs) are organic chemicals that have a high vapor pressure at ordinary room temperature. VOCs are widely used because they are important substances as solvents and fuels. However, when released into the environment, these cause health hazards such as pollution. So VOCs are regulated by law in some countries. FUJIFILM Wako provides 4 types of VOC mixture standard solutions. Especially, 25 VOC mixture standard solution is traceable to SI traceable Japanese measurement standards (Japan Calibration Service System; JCSS).

Stinking substances cause unpleasant odors and may damage the living environment. In Japan, 22 stinking substances have been designated by the Environment Agency, and all factories within the regulated area designated by the each local government are required to measure stinking substances to considerate of the surrounding environment.
FUJIFILM Wako provides a variety of standard solution and columns to analyze stinking substances.

What is JCSS?

The JCSS reference material is traceable to the specified SI traceable reference material, which is the national measurement standard of Japan, manufactured by the designated calibration institute ”Chemicals Evaluation and Research Institute : CERI” under the Measurement Law, and has a JCSS symbol by the JCSS registered business operator. It is provided to the user as a reference material, which attached a certificate with JCSS symbol. We have been certified by IA Japan as an international MRA accreditation operator, and we have issued a calibration certificate with the JCSS certification symbol. The values ​​described in this calibration can be accepted internationally through the MRA of ILAC/APAC.
