DYNAMIC HEAD SPACE SYSTEM IN EXPERIMENTAL RESEARCH METHODOLOGY - USE IN ANALYSIS OF RADIO-INDUCED HYDROCARBONS

Head space systems are used to analyse volatile compounds in liquid or solid samples without preliminary extraction. The experimental resear ch methodology has been used to obtain the optimal performances of the system. After determination of the main factors, the modelisation has been made using a Doehlert experimental matrix. Study of the response equation, and the canonic equation, leads to the values of factors wh ich optimise the experimental response, and permit to obtain a total d esorption of the volatile compounds contained in the sample.
