MRA/JCSS-certified products

As a JCSS-accredited calibration solution provider, we offer a wide range of standard solutions traceable to Japan’s national measurement standards. Our certified products support high-precision calibration in key measurement categories, including:

  • ○ pH
  • ○ Metals and non-metals
  • ○ Volatile organic compounds (VOCs)

Each standard solution is issued with a certificate bearing the official “JCSS” accreditation symbol, ensuring reliability and traceability for laboratory testing and calibration.

Our accreditation is managed by IAJapan, an internationally recognized body under the National Institute of Technology and Evaluation (NITE). IAJapan is a signatory to the Mutual Recognition Arrangements (MRAs) of both ILAC (International Laboratory Accreditation Cooperation) and APLAC (Asia-Pacific Laboratory Accreditation Cooperation). This recognition ensures that our JCSS-accredited certificates are accepted by laboratories and regulatory authorities worldwide.

ASNITE-Certified Reference Materials (CRMs)

We are proud to be authorized as a standard substance manufacturer under the ASNITE Accreditation System, administered by IAJapan. This prestigious accreditation demonstrates our compliance with internationally recognized standards, namely:

  • ○ ISO Guide 34 (now ISO 17034): General requirements for the competence of reference material producers
  • ○ ISO/IEC 17025: General requirements for the competence of testing and calibration laboratories

As an ASNITE-accredited producer, we are certified to provide high-quality, reliable standard substances with full traceability to national and international measurement standards. Each product is accompanied by a certificate that clearly specifies measurement uncertainty, recognized through the APLAC Mutual Recognition Arrangement (MRA).

This accreditation serves as solid proof of our technical competence, quality assurance, and global credibility in the production and supply of certified reference materials.

Inorganic Standards Multi-Element ICP & MS

With the rapid advancement of instrumental analytical technologies, simultaneous multi-element analysis using ICP-AES (Inductively Coupled Plasma Atomic Emission Spectroscopy) and ICP-MS (Inductively Coupled Plasma Mass Spectrometry) has become a standard in many laboratories.

To support these cutting-edge techniques, we supply a comprehensive range of high-purity standard metal mixing solutions, precisely formulated to meet the calibration and validation needs of modern elemental analysis. Our solutions ensure accurate, reproducible results and are traceable to national and international measurement standards, making them ideal for environmental testing, industrial quality control, and academic research.
