Measuring odor concentration · consultants

Odor concentration is an odor's pervasiveness. To measure odor sensation, an odor is diluted to certain amounts to reach a detection or recognition threshold. The detection threshold is the concentration of an odor in air when 50% of a population can distinguish between the odorous sample and an odor free ...

Dynamic Light Scattering Services

Dynamic Light Scattering (DLS) is a commonly used term to describe a technique which measures the particle size and estimated distribution of submicron particulate systems. In addition, the terms Photon Correlation Spectroscopy (PCS) and Quasi-Elastic Light Scattering (QELS) have also been used historically to refer to the same analytical principle. By any name, the technique is widely recognized ...
