The method for determination of volatile organic compounds emitted by insulating materials such as: expanded polystyrene, glass wool and polyolefin sheetings has been described. Emission has been measured using environmental test chambers. For the isolation and preconcentration of the emitted compounds one used sorbent trapping (Tenax TA) followed by thermal desorption. Volatile organics were determined...
Direct thermal desorption as a method for isolation and preconcentration of trace amounts of brominated hydrocarbons is described. This technique involves use of heat and inert gas flow. The analytical performance of this method is presented for the determination of 1,2-dibromoethane. This compound was determined in the samples of the tea, rice, peanuts and walnuts, which are purchased locally. Suitable...
