- W8306992 abstract "The purpose of this research program was to identify sources of error in the measurement of gas/particulate aerosols using sampling probes. The objectives of the program included: conducting a literature review and developing an analytical model for treating the errors in sampling measurements under turbulent, anisokinetic flow conditions; performing experimental studies to determine the measurement error for particles in the respirable range; and, reviewing the status of various optical methods for in situ measurements of both particle size and concentration. A series of measurements has been completed to determine the sampling error for particles with a Stokes number of 0.02. The experimental results have led to the conclusion that an inline, or straight, sampling probe is preferable to a hooked probe of the standard type used in obtaining measurements in stacks and flues. Metal probes are shown to be preferable to the use of glass probes due to charging effects, although the glass probes provide visual information on deposition patterns in the probe body. Turbulent deposition inside the probes accounts for up to 50% of the particulate aspirated into the inlet for high rates of sampling. Up to 20% of the collected sample may be impacted on the probe tipmore » due to turbulence. It is also shown that the deposition pattern on the filter paper used to obtain the sample is a function of the size distribution of the particulate in the aerosol. If the aerosol is highly polydisperse, a size segregation occurs on the collection filter whereby the larger diameter particles are collected on the outer edges of the filter. The size segregation of particles must be considered when examining filters to obtain information about the aerosol. Other comments on the analysis of the filters are presented in an extended appendix summarizing these experiments. (LCL)« less" @default.
