PERFECCIONAMIENTOS EN DETECTORES DE IMPUREZAS GASEIFORMES EN EL AIRE

摘要

Gaseous impurities in air are detected by a gas sensor whose material (1) consists of a dried piece of gel containing no impurities with homogeneous distribution of particles and interstices. The material ensures a high gas permeability and response sensitivity at low operating temperatures. The most favourable 3-dimensional shape of the material for gas detection is cut out of a gel slab (16).
