WebNov 20, 2024 · Light obscuration is the method of choice listed in the pharmacopoeias for the analysis of subvisible particles in parenteral products. The sample is drawn into the system's sensor through a needle or sample tube. Particles passing a laser beam block a certain amount of light and produce a “shadow” on a light-sensitive detector. The area of ...

WebVisible-light astronomy is part of optical astronomy, [clarification needed] and differs from astronomies based on invisible types of light in the electromagnetic radiation spectrum, such as radio waves, infrared waves, ultraviolet waves, X-ray waves and gamma-ray waves. Visible light ranges from 380 to 750 nanometers in wavelength . WebAug 9, 2016 · We use the obscuration, or the amount of light blocked or scattered by the particles, as a measure of the concentration of particles within the Mastersizer 3000. We recommend ranges of obscuration based on the expected particle size, which are different for wet and dry dispersions.
WebLight blockage is usually known as light extinction (LE) or light obscuration, which enables high-resolution particle sizing and counting down to 1 µm. The required mode of detection is less than 1 µm light scattering, where the light is detected after being scattered by smaller submicron particles, and then the particle size is acquired.

WebJun 17, 2014 · Light obscuration (LO) is the current standard technique for subvisible particle analysis in the quality control of parenterally administered drugs, including therapeutic proteins. Some of those, however, exhibit high viscosities due to high protein concentrations, which can lead to false results by LO measurements.
