Before a source analysis program is undertaken, it is important to decide which information is really required. Sampling sites must be selected with care. Choice of the site can significantly affect accuracy and cost. Care must also be taken in the selection of sampling points at the site. Measurement usually involves the deterrnination of temperature, concentration, and characterization of the gas contaminants. It also requires the mass rates of emission of each contaminant, therefore concentration and volumetric flow data are required. [Pg.299]

Published data on PCDD/Fs in the environment of the PRD is still limited. A short-term sampling scheme was conducted to determine the levels of particle-bound polychlorinated dibenzo- -dioxins and dibenzofurans (PCDD/Fs) in Guangzhou atmosphere and evaluate the impact of PCDD/ Fs to inhabitants. Samples were collected from four different districts of Guangzhou. The results showed that industrial activities had more influences on levels of PCDD/Fs in the sampled districts. The mean PCDD/Fs concentrations (i.e., mean I-TEQ values) of Huadu district, Liwan district, Tianhe district and Huangpu district were 3815-26,530 fg m-3 (104.6-769.3 fgl-TEQ m-3). Emission source analysis indicated that small diffuse sources were relatively important (Yu et al., 2006). [Pg.304]

A commercial explosive trace detection system, Hitachi DS-120E, based on a quadrupole mass spectrometer was built [7], Ionization is carried out by corona discharge and APCI. Sampling is carried out by wiping surfaces on suspicious objects for traces of explosives. The wipe sheet is inserted into the detection system, where it is heated in order to desorb the trace explosives into the ion source. Analysis time is 5-10 s. [Pg.48]

When used to encode and process speech, the channel vocoder explicitly makes an assumption that the signal being modeled is a single human voice. The source analysis block extracts some parameters about the fine spectral detail, such as whether the sound is pitched (vowel) or noisy (consonant or... [Pg.79]

Since about 1955, organic solvents have been increasingly used as media for the operation and study of electrode processes. They now find application in many areas of electrochemistry, e.g. power sources, analysis and synthesis. The principal reasons for choosing organic solvents are usually one or more of the following ... [Pg.748]
