Jan 7, 2020 · We have developed an updated and automated pressure nephelometer that utilizes visible-infrared (Vis-IR) spectra to accurately quantify GV critical collapse pressure, critical collapse pressure distribution, and cell turgor pressure.

Feb 11, 2020 · The Pc50 parameter (“critical pressure”) characterizing each suspension identifies the overpressure (with respect to atmospheric pressure) at which the absorbance of the microvesicles suspension drops to half of its initial value.

pressure nephelometer design that (i) minimizes interferences from color, particle density, particle size, and the presence of stray light, (ii) improves precision in the

Nephelometer calibration involves measuring the scattering coefficients of dry CO 2 gas introduced into the system and comparing them with known values from literature that are adjusted for calibration conditions (temperature, RH, air pressure) (Anderson et al. 1996).

Mar 26, 2024 · The resistance of MBs to pressure was evaluated using an in-house-developed pressure nephelometer by measuring absorbance (Spectrophotometer Jenway 6300, Cole Parmer, Vernon Hills, IL, USA) as a function of increased hydrostatic pressure.

Jan 1, 1988 · The critical pressures of suspensions of isolated gas vesicles can be determined by the pressure nephelometer. The gas vesicle suspension, preequilibrated with air, is placed in the thick-walled glass tube and the pressure-tight coupling is attached.

Nov 1, 2019 · Here, we present a multiplexed instrument capable of quantifying the relative abundance of cyanobacteria based on the signal generated from the presence of intracellular gas vesicles specific to...

Nov 1, 2019 · We have developed an updated and automated pressure nephelometer that utilizes visible-infrared (Vis-IR) spectra to accurately quantify GV critical collapse pressure, critical collapse pressure distribution, and cell turgor pressure.

Feb 15, 2024 · The TSI nephelometer is designed to measure the scattering and backscatter coefficient at three wavelengths, 450, 550, and 700 nm and can be fitted with size selective inlets of the operator's choice. Its minimum detectable limit …

Nephelometers are used to measure turbidity, haze and suspended solids on a variety of liquids. Also available are single meters that combine turbidity and colorimetric measurements to test the most important parameters of drinking water: turbidity and free/total chlorine.
