Abstract: A sample in a gas state to be measured is forced to impinge on a structure in which a change in a characteristic including a mechanical deformation, an optical change, an electric change and a magnetic change is exerted due to the impingement of a gaseous sample, a gasified liquid sample or solid sample to cause at least one of changes in characteristics including a mechanical deformation, an optical change, an electric change and a magnetic change; and the molecular weight of the sample in a gas state is obtained.

Abstract: According to improvement of the receptor layer of various sensors of the type for detecting physical parameters (for example, a surface stress sensor, QCM, and SPR), all of high sensitivity, selectivity, and durability are achieved simultaneously. A porous material or a particulate material, e.g., nanoparticles, is used in place of a uniform membrane which has been conventionally used as a receptor layer. Accordingly, the sensitivity can be controlled by changing the membrane thickness of the receptor layer, the selectivity can be controlled by changing a surface modifying group to be fixed on the porous material or particulate material, and the durability can be controlled by changing the composition and surface properties of the porous material or particulate material.
