nephelometer. Aerosol Sci.
Nephelometers detect particles, then measure light scattering by the particle, and using assumptions about optical properties and density, assign a size to each particle to produce a mass concentration estimate--not a mass measurement.
At several of the other 12
nephelometer locations, much smaller peaks were apparent in PM[sub.2.5] and PM[sub.10] after the burns were initiated, up to 57 μg per cubic meter of PM10 within the hour.
Values were considered high if cholesterol was greater than 200 mg/dl, LDL-c greater than 130 mg/dl, triglycerides greater than 100 mg/dl in age ?10 years and greater than 130 mg/dl in age10-19 years and HDL was considered low if less than 35 mg/dl.13 ApoA1, Apo B100 were evaluated using a Behring
nephelometer. The accepted Apo A1 level (SD) was 133 (27) mg/dl in age less than two years and 143 (18) mg/dl in age greater than two years.
Another valuable technique is to monitor the dust and fume levels in real time by using a
nephelometer or light scattering device.
The SidePak was calibrated against a SHS-calibrated
nephelometer, which had been previously calibrated and used in similar studies.
Also known as a turbidimeter, the
nephelometer is an opto-electronic instrument that determines the turbidity of a liquid, or the quantity of suspended particles in a liquid.
Because blood contamination during perilymph sampling cannot be completely avoided, total IgG and albumin were measured with a
nephelometer. We calculated the blood contamination of the perilymph based on a serum-to-perilymph gradient of 35-to-1.
* Equal to or less than 5
nephelometer turbidity units (NTUs),
According to Jones, ISP's Wayne, NJ-based brewmaster can also do on-site analysis at any client brewery, using a piece of equipment called a
nephelometer. "This device allows on-site analysis of stabilization regimes for the first time," Jones says.
Ragent's
nephelometer also noted something like a light fog lower down where the N[H.sub.4]SH should condense, but there's no compositional signature to confirm it.
furnishes a portable kit that uses a portable, hand-held and battery-powered spectrophotometer that converts to a
nephelometer for turbidity measurement and a DPD (N, N-diethyl-p-phenylene-diamine) chlorine residual analyzer.
