A common technique for evenly dispersing dry powder on SEM stubs, the Nebula Particle Dispenser, becomes accessible. By creating a particle monolayer and avoiding particle clusters while keeping the structure of delicate particles, the Nebula ensures the optimum sample preparation.
With the help of the Particle Metric software and this dry powder disperser, the user may easily obtain the best results. The user can collect and examine data on particle size and morphology thanks to the special integration of Particle Metric and the Nebula. A little amount of powder is poured into the well at the top of the Particle Dispenser’s cylindrical reservoir.
When vacuum is supplied, the vacuum seal is abruptly disrupted by a sudden trigger. Instantaneously, the sample is drawn into the vacuum reservoir. Agglomerates are broken up and the particles are evenly distributed throughout the reservoir volume as a result of the sudden suction’s turbulent flow, which has high Reynolds numbers and high shear forces.
As the reservoir has very little internal force, equilibrium is reached after a short period of time. Following that, gravitational sedimentation imitates the action of isokinetic sampling, and the particles create a consistent monolayer on the slide.
Global nebula particle dispenser market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The Lagrangian particle dispersion model FLEXPART was created for predicting the long-range and mesoscale dispersion of dangerous compounds from point sources, including those discharged following a nuclear power plant accident.
The model has developed into a comprehensive instrument for multi-scale atmospheric transport modelling and analysis during the past few decades, drawing a large user base from all around the world.
A wide range of atmospheric gases and aerosols, including greenhouse gases, transient climate forcing agents like black carbon and volcanic ash, as well as the atmospheric branch of the water cycle, have been included in its application field.
For many years, FLEXPART has offered the option of regressing air concentrations at receptor locations backward in time. This capability has now been expanded to include deposition values and may prove useful, for example, in the interpretation of ice core reading.
