Theoretical Analysis of PM2.5 Mass Measurements by Nephelometry
With the recently promulgated PM2.5 mass standards, a need has appeared for continuous PM2.5 mass measuring instrumentation to complement standard filter based aerosol samplers. It is generally accepted that in most cases, the PM2.5 mass distribution and light scattering is dominated by particles with diameters in the size range 0.1–1.0μm. Early field studies indicated a reasonable correlation ...
متن کاملNephelometry of apolipoprotein B in human serum.
We studied the development of light scattering in the reaction between anti-apolipoprotein B and apolipoprotein B in intact very-low-density lipoproteins (I) and low-density lipoproteins (II) as well as in lipoproteins treated with lipases, and found considerable differences in the kinetics of the immunoreaction for the two lipoprotein classes. Pre-incubation with triglyceride lipase and choles...
متن کاملLaser Nephelometry Measurement of Fibrin Polymerisation
Ever since the description by Green' of a modification of the colorimetric method reported by Soria2 to determine the kinetics of fibrin polymerisation induced by reptilase was published, no attempts have been made to improve the sensitivity of the method. The controversial association of the abnormalities of fibrin polymerisation detected by traditional methods with the presence and severity o...
متن کاملAngular truncation errors in integrating nephelometry
Ideal integrating nephelometers integrate light scattered by particles over all directions. However, real nephelometers truncate light scattered in near-forward and near-backward directions below a certain truncation angle ~typically 7°!. This results in truncation errors, with the forward truncation error becoming important for large particles. Truncation errors are commonly calculated using M...
متن کاملRate nephelometry and radial immunodiffusion compared for measuring serum prealbumin.
We compared a rate-nephelometric method and a radial immunodiffusion (RID) assay for measurement of prealbumin (transthyretin) in 55 samples of serum from healthy children. The mean prealbumin concentration as measured by the Beckman Auto ICS nephelometer was 188 mg/L (range 128-350); the mean by RID was 221 mg/L (range 125-419). This difference was statistically significant by Student's t-test...
