Odor Evaluation Technology

Various evaluation devices and skills to make full use of them

Deodorizing capability imparting technology is one of Suminoe Textile's flagship technologies. To work on the research and development, it is essential to analyze and evaluate odor. We have analytical equipment suited to different odor types, concentrations, and indoor environments.

Our Technical Center is equipped with instruments necessary to analyze and evalute odors. Staff there are familiar with the use of the odor analytical instruments and preprocessing techniques for odor sample evaluation, and utilize the expertise for a wide range of odor analysis and evaluation. By using various devices to evaluate odor, we are involved in the development of suitable deodorizing technologies for various environments.

Equipment 1: odor analysis equipment

  • Gas chromatograph (GC)
  • Gas chromatograph mass spectrometer (GC-MS) + optional sniffer unit
  • High performance liquid chromatography (HPLC)
  • Photoacoustic multi-gas monitor
  • Odor identification systems

Equipment 2: a group of deodorization test chambers

  • Measurement boxes (30 L/250 L in capacity and JEMA-compliant 1 m3
