In many applications a multitude of different gases may occur which have to be identified and analyzed simultaneously, for example in detecting cable fire in a cable slot at a very early point of time but with high discrimination to other gases. But well introduced calibration and evaluation procedures are only designed to analyze only one gas or gas mixture. A new and efficient mathematical procedure called SimSens was developed to overcome this drawback. A short outline of SimSens and the validation with real data of four gases and one gas mixture is presented and the ability of simultaneous gas identification and reliability respective accuracy of analysis is discussed.
