Sensors to detect CO based in SnO. Sensores para detectar CO basados en SnO  

Energy Technology Data Exchange (ETDEWEB)

The development of solid state chemical sensors, and more specifically of gas sensors, is carried out with great strength in the present time since the environmental pollution and the security in work and domestic ambient are problems of great interest and social impact. The main fields of application, are: automobile, domestic sensors, control of industrial process, bio medicine, environment. These chemical sensors are experimenting a great advance because of the advantages they offer, as low cost, simple operation, possibility of measure continuous and ''In situ'' and small size, in contrast with analytical techniques that need complex instrumentation and large size equipments. In the present work, a sensor for CO detecting concentrations as low as 50 p.p.m., is studied showing great interest since this gas is highly toxic even to such a low concentration. (Author)

Qualitative aspects in the projects that are developed in the Instituto de Investigaciones Electricas; Aspectos cualitativos en los proyectos que se desarrollan en el Instituto de Investigaciones Electricas  

Energy Technology Data Exchange (ETDEWEB)

The globalization of markets has generated more options of purchase of all type of goods and services, these options have generated opportunities and threats for all the companies and have looked for the satisfaction of the client as a strategy to remain or incursion into the global market. The Instituto de Investigaciones Electricas (IIE) is not the exception and therefore it looks for the identification of the qualitative aspects and to systematize its application in the projects that executes by means of the implantation of a system of quality assurance based on the series of ISO 9000 Standards. Some examples are described to identify the qualitative aspects of the projects that are developed in the Institute.
