An intelligent gas sensor has been developed using thick‐film techniques to create a semiconducting oxide surface with carefully varied catalytic properties. An integral heater causes the surface to react with combustible gases and the resulting resistance map of the surface forms a signature that can be related to the functional groups present in the gas. For example, alcohols, ketones and alkanes have distinct, recognisable signatures on one sensor model.

The Benelux chapter has made a habit of organising meetings with a scientific and commercial accent more or less alternately. This approach has proven to be successful in the past three years. The 1986 Autumn meeting will be another display meeting. A number of papers will be presented by suppliers of materials and equipment for the hybrid and surface mounting industry. In a 300 m2 exhibition room about 25 companies will display their products. The programme of the day leaves ample opportunity for meeting colleagues and suppliers. The meeting will be held in the ‘Jaarbeurs Vergadercentrum’ in Utrecht on 16 October from 9.30–17.00. The annual ISHM‐Benelux general membership meeting will precede the lectures.
