WebSep 13, 2024 · The principle behind mass photometry is simple: a single molecule in contact with a measurement surface (e.g. a coverslip) exposed to a beam of light produces a small but measurable light scattering signal, which is directly proportional to the molecule’s mass. The greater the mass of the molecule, the more intense the signal (Fig. 1). WebA photometer is an instrument that measures the strength of electromagnetic radiation in the range from ultraviolet to infrared and including the visible spectrum. Most photometers convert light into an …

Webthe commercially available light scattering photometers. Adaptation and new design of photometers A number of adaptations improving the performance of commercial light scattering photometers have been suggested (e.g., Ref. 6-8). Some authors prefer homemade photometers tailored to meet their specific needs (Ref. 4, 9-12).
WebThe Rigel RI7001 digital photometer is the best choice for testing the integrity of HEPA filters. Using the light scattering method, the Rigel RI7001 provides real-time integrity through detection of aerosol concentration upstream and downstream. The 3.5″ LCD on the base unit provides an easy to read interface displaying sample concentration ... The measurement of scattered light from an illuminated sample forms the basis of the so-called classical light scattering measurement. Historically, such measurements were made using a single detector rotated in an arc about the illuminated sample. The first commercial instrument (formally called a "scattered photometer") was the Brice-Phoenix light scattering photometer introduced in the mid-1950s and followed by the Sofica photometer introduced in the late 1960s.
