“…Most of this work was done on hazardous waste incinerators, where CEMs have the potential to provide on-line feedback control data for optimising plant performance. Despite the advances in such techniques, none have been found to meet the quality requirements for regulatory endorsement (Lemieux et al, 1998;Woskov et al, 2000;Hill et al, 2002). Recent developments in end-of-pipe monitoring technologies have either been in laser or microwave induced plasma techniques (Hill et al, 2002;Buckley et al, 2000;Woskov et al, 2000), or in Argon-ICP-OES (Hassaine et al, 2001;Seltzer, 2000).…”

“…The account of methods for the analysis of inorganic particles presented here is by no means meant to be exhaustive, and it should be noted that improvements in techniques for the analysis of inorganic particles in air appear regularly in the literature. An example is instrumentation developed for Continuous Emission Monitoring (CEM) of metal aerosols in air with no sample pre-treatment stage (Lemieux et al, 1998;Gomes et al, 1996). Although developed for the analysis of outdoor air, these instrumental techniques for the purpose of real-time monitoring of elemental composition of aerosols in theory offer an effective way of monitoring pollutants in outdoor and indoor air.…”

Electron Microscopy-Based Microanalysis of Airborne Particles IntroductionElectron microscopy (EM), namely transmission and scanning, is the most common technique used for particle analysis, at both the morphological and chemical levels; it is assumed that the reader is familiar with the basic principles of electron microscope design and operation and only the practical applications will be considered. In terms of particle identification based on morphology, transmission electron microscopy (TEM) is the more robust system, especially when dealing with airborne particles that are submicron in size. TEM will yield information on the ultrastructure, providing a two-dimensional interpretation of a particle. In contrast, scanning electron microscopy (SEM) is more limited to airborne particles that are microns in size and will produce information about a particle's surface structure or a three-dimensional interpretation.The added bonus of EM is its capacity to determine the elemental composition of airborne particles, at both the individual and bulk particle levels. Several analytical techniques are available for the elemental characterization of specimens within the electron microscope (e.g. X-ray analysis, Auger electron spectroscopy, and electron energy loss spectroscopy). For all such techniques, a signal is produced by either direct electron bombardment, or by interaction with auxiliary excitation sources (e.g. X-rays) and collected in appropriate detectors (i.e., an energy dispersive spectrometer [EDS]), to yield specific information about the elemental features of a specimen. In the case of particle analysis, elemental characterization is best achieved by means of X-ray detection using a technique more commonly known as electron probe X-ray microanalysis (EPXMA). X-rays within the electron microscope are generated by the interaction of the electron beam with individual atoms in the specimen (e.g. characteristic X-rays). These X-rays carry information about the elemental composition of the specimen in the region that is being irradiated and consequently provide a means of correlating structural information with elemental content. Therefore, in theory, X-ray microanalysis is possible using any electron microscope fitted with a suitable detector system, and this is generally true for qualitative X-ray microanalysis. Quantitative X-ray microanalysis is a 105 2.4

“…For flow monitors, the relative accuracy, derived from measurements in units of standard cubic feet per hour, must be 15% or less [7][8] . More specifications and test procedures for continuous emission monitoring systems of flue gas emitted from stationary sources can be referenced in China EPA HJ/T 76-2007 rule [3] and USA EPA CFR Title 40 Parts60 and Parts75 [7,9] .…”

Continuous Emissions Monitoring Systems (CEMS) permanently installed for selected processesrequire initial and periodic quality assurance audit tests to ensure that they are functioning properly and reporting emissions accurately. Depending on the industry and process type, there are several sets of regulations that dictate the exact QA/QC requirements that the CEMS must meet. Measurement data by CEMS is a legal base to charge for pollutant emission. But the great masses of CEMS have some problems of high data drift and low measurement accuracy etc. For evaluating CEMS Relative Accuracy, we simultaneously compared SO 2 /NOx and Dust monitoring systems with CEMS and normal handmade sampling method at different boiler load. It draws a conclusion that Relative Accuracy Test Audit (RATA) of SO 2 /NOx monitoring systems goes beyond criterion.
