The standard gas samples used for calibrating mud logging instrument in China have been still existed the problem of un-integrated and abnormal, thus constrained the accuracy and comparability of mud logging interpretation parameters on certain extent.

The application of air sampling early smoke detection system in heat-engine plant

This paper introduces an air sampling smoke detection system of the high sensitivity and performance,structural characteristics and working principle and mainly focuses on the application of this system in the large space.

Through analyzing the factors which influence the safety of traditional buildings and these methods to control fire fighting system,electrical safety,indoor thermal and air quality,air sampling is recommended as one effective and economical method to detect and monitor fire fighting and indoor air quality.
