DUST DISPERSER
Dust Generators SAG 410 (TOPAS GmbH)

General-purpose dry powder disperser that may be used for a variety of  applications in aerosol and powder science, industrial processes and quality assurance tasks.

The technique for the dispersion of dry dust and powders comprises two steps, the continuous supply of material to the disperser and the dispersal of the material as an aerosol.

ATOMIZER

Atomizer Aerosol Generator ATM 210, 210/H (TOPAS GmbH)

This special model facilitates generation of aerosols into pressurised vessels up to 10 bar.

It produces aerosols with known properties in accordance with the guideline VDI 3491. The generated polydisperse aerosols are mainly below 1 µm with an excellent stable particle size distribution.Suitable liquids are e.g. DOP, Emery 3004, DEHS, salt soultions and it can be also used to disperse PSL reference materials.

Atomizer Aerosol Generator ATM 220, 225 (TOPAS GmbH)

An aerosol generator for producing a test aerosol with defined characteristics especially for qualitative tests of filters for suspended matter (HEPA and ULPA filters), function test at laminar flow boxes and acceptance measurement in clean rooms.

It produces aerosols with known properties in accordance with the guideline VDI 3491. The generated polydisperse aerosols are mainly in the size range 0.2 to 0.5 µm with a very high permanence of the particle size distribution and a defined and high particle number concentration.

 A further range of application for aerosol generators is calibration of measuring devices and visualization of currents. That enables measurements of local velocities and flow profiles of the tracer particles by means of optical methods.

Atomizer Aerosol Generator ATM 240, 241, 242 (TOPAS GmbH)

The generator is designed for generation of tracer particles, verifying measurements in very large clean rooms and for tests of HEPA and ULPA-filter media.

It produces aerosols with known properties in accordance with the guideline VDI 3491. The generated polydisperse aerosols are mainly below 1 µm with an excellent constant particle size distribution and defined and high particle number concentration.Suitable liquids are e.g. DOP, Emery 3004, DEHS, salt soultions and it can be also used to disperse PSL reference materials.
By varying of nozzle pressure, number of switched-on nozzles and the aerosol temperature (besides ATM 241) one can adjust both particle production rate and particle size distribution in a wide range.

MONODISPERSE

Condensation Aerosol Generator SLG 250 (TOPAS GmbH)

The instrument can be used for generation of high-concentration up to106 particles/s of monodisperse aerosols with a reproducible particle size in a wide range.

The principe is based on a controlled heterogenous condensation which produces spherical and virtually electrically neutral particles. For DEHS aerosols, the particle size range is 0.1 to 5 µm.
