Aerosol Generator ATM 221/D

The ATM 221/D Atomizer Aerosol Generator serves for the generation of aerosols from liquids, especially from suspensions.

Standards

The generation of polydisperse aerosols with increased quantities of supermicron particles (≥ 1 µm) is typically done by dust generators. An elegant and more precise alternative to dry dispersion is the aerosolisation of suspensions with subsequent drying. In light of this, the ATM 221/D was especially developed for the calibration and validation of PM sensors.

Benefits

• removable dispersion unit for easy cleaning
• operation of dispersion unit away from base station (e.g. within thermostats)
• including magnetic stirrer for stabilisation and homogenisation of suspensions/solutions
• additional ball valve for start-stop operation at adjusted operational pressure

Applications

• calibration and validation of PM sensors and other aerosol technologies
• determination of fractional separation efficiency of filter elements and filter media
• material characterisation and research

Accessories

• diffusion dryer (DDU 570/L, DDU 570/H)
• ultrasonic desintegrator (UDS 751)
• aerosol substance (DEHS)
