Static air sampling
WebHeadspace analysis is a technique for sampling and examining the volatiles associated with a solid or liquid sample. The actual headspace itself is the volume of vapor or gas above the sample. For most headspace analysis purposes the sample and its associated headspace are held within an enclosed container (Figure 1).Often, it is the volatiles that are of primary … WebThis paper describes the development and laboratory testing of a new static dust sampler for airborne total dust in workplaces. Particular attention is paid to designing the sampling head and entry consistent with the concept of inspirability which in turn defines a biologically-relevant aspiration efficiency.
