Unlike liquids, where you can control the pathlength or solids (tablets), where either diffuse transmission
or reflection may be used, semi-solids present unique process analysis problems.
The light diffuse transmission
results for the first type of films are shown in Figure 2, it shows little variation by changing the concentration and the only additive that reduces transmission of light is the red pigment significantly reducing by half.
Optical properties such as haze, total transmission, and diffuse transmission of samples were measured in a 1-mm-thick injection molded plaques on ColorQuest II Hazemeter (HunterLab, USA) as per ASTM D1003-95 standard.
where total transmission (TT) is the sum of the diffuse transmission (DT) and the direct transmission.
Figure 2 shows that the decrease in percentage haze value is directly proportional to the percentage decrease in the diffuse transmission in the TPA blend series.
However, bias error arises in the case of diffuse transmission measurements because the scattered radiation originating at the sample is not distributed uniformly over the surface of the integrating sphere and the radiation sensed by the detectors includes the first reflection of this non-uniform distribution.
m] with respect to [theta] it was anticipated that the diffuse transmission component, [[tau].
Two different NIR sampling modes, diffuse reflectance and diffuse transmission
, are commonly used for a variety of tablets.
Other beliefs may be deemed heretical if they involve the contradiction of scriptural texts handed down through diffuse transmission
(tawatur) or subject to consensus ([TEXT NOT REPRODUCIBLE IN ASCII]), engendering a preponderant probability that they represent the actual words or practices of the Prophet.
However, even these units offer only specular transmission mode, while higher-end benchtops have both specular and diffuse transmission
capability - the latter being considered more precise.
First, some diffuse transmission can be expected, however small, as [theta] [right arrow] 90[degrees] for every roller blind material.
bb]([theta] = 0) and also noting that the structure only produces diffuse transmission, the apparent transmittance of the roller blind structure,[[tau].
