The protective specifications ( wavelengths and optical densities ) are usually printed on the goggles, generally near the top of the unit.
22.
In the European Community, manufacturers are required by European standard EN 207 to specify the maximum power rating rather than the optical density.
23.
It calculates ROD ( relative optical density ), luminance, concentration, the area of region of interest, ligand concentration, and the amount of radioactivity.
24.
While most turbidostats use a spectrophotometer / turbidometer to measure the optical density for control purposes, there exist other methods, such as dielectric permittivity.
25.
Variable tint or photochromic lenses increase their optical density when exposed to UV light, reverting to their clear state when the UV brightness decreases.
26.
In this study the KIE is calculated from the reaction rate constants for regular 2, 4-dimethyl-3-pentanone and its deuterated isomer by optical density measurements.
27.
"' Densitometry "'is the quantitative measurement of optical density in light-sensitive materials, such as photographic paper or photographic film, due to exposure to light.
28.
If I have to read an enzyme-linked immunosorbent assay microplate, is it ok to obtain optical densities with a spectrophotometer instead of a microplate reader?
29.
The institute's testing puts the cartridges through 22 procedures to measure fill weight, dry time, optical density, range of perceived color, page yield and other benchmarks.
30.
Optical density ( OD ) is directly proportional to the biomass in the cell suspension in a given range that is specific to the cell type.
