The results of many different studies have demonstrated unequivocally that the quality of indoor air is often much worse than that of atmospheric air (outdoor). One of the main groups of chemical compounds present in indoor air, with proven harmfulness to health,are volatile organic compounds (VOCs). VOCs present indoor comprise a wide variety of hydrocarbons and hydrocarbons derivatives including aliphatic, aromatics, alkylbenzens, ketones, chlorinated and polycyclic hydrocarbons. In indoor environment such substances canbe emitted by building materials and household equipment.In order to identify the source of emission of organic compounds, miniature passive emission chambers, known as passive flux samplers, are being used. These instruments enable the passive intake of samples of analytes emitted from the flat surfaces of building materials and interior equipment. Such apparatus offers an alternative approach to the time-consuming and labor-intensive investigations using expensive stationary emission test chambers.This study present a new type of miniaturized passive emission chamber which was designed for in-situ screening primary sources (building and internal materials) of VOCs emission.
