At the 15 targeted nephelometer
locations, plus an additional 14 locations near the burns, trained local personnel placed passive samplers (which did not require a field operator or electricity) to measure particulate matter (RJ Lee Group, Monroeville, PA) and naphthalene (SKC Product Code: 575-003, Eighty Four, PA) for 24 to 120 hours and then sent the samplers to our laboratory for analysis.
have proven useful in many different industries including: sewage treatment; environmental monitoring; food and beverage; chemical process control; metal works; and paper and pulp processing.
FLC assays were performed on a Dade Behring BN II nephelometer
with FLC reagent sets from The Binding Site (Birmingham, UK).
5]) concentrations and using the Radiance nephelometer
(model 903; Radiance Research, Seattle, WA) at eight residences for continuous light-scattering measurements.
Field evaluation and quality control of personal nephelometers
in indoor, outdoor and personal environments.
are also expensive and are not used in many in small- and medium-sized clinical laboratories.
The assay is now available on several different platforms, including the Immage[TM] Protein System (Beckman Coulter), the BNII[TM] and BN ProSpec[TM] Nephelometers
(Dade-Behring), the Hitachi 917 (Roche Diagnostics), and The Binding Site MiniNeph system.
We employed portable nephelometers
providing continuous measurements and electronic data recording to optimize the temporal resolution of indoor particle levels in these homes.
Compared with the PENIA developed for the Dade Behring (Milton Keynes, United Kingdom) nephelometers
Specific serum proteins were quantified by BN 100 or BNA nephelometers
from Behringwerke AG and by Array 360 and/or Itiitnage nephelometers
from Beckman Instruments.
The overwhelming majority of clinical assays in the US are performed by immunonephelometry, utilizing the Beckman or Behring nephelometers
The two nephelometers
differ in how they measure the protein concentrations.
