The aerosol generator ATM 240/S was developed to produce aerosols from suspensions (e.g. salt solutions, sugar solutions) with high quantities of particles > 1 µm.
Standards
ISO 16890-2
VDI 3491-2
By operating the generator with aqueous potassium chloride suspensions (> 5 wt.-%), solid aerosols are formed that fulfil the requirements of ISO 16890-2 at moderate test flow rates up to 64 m³/h.
Benefits
- stable aerosol generation over time according to VDI 3491-2
- aerosols with high particle number concen-trations in the size range of 0.01 – 10 µm
- compact, space-saving design with implemented aerosol dryer
- fast operational readiness (short initial phase, easy to clean and maintain)
Applications
- fractional air filter separation efficiency testing according to ISO 16890-2
- calibration and validation of aerosol-analytical instruments
- medical research on coarse salvia aerosols (mass median aerodynamic diameter MMAD up to 8 µm)
Accessories
- electrical aerosol neutralisation system (EAN 581) for particle discharge
- laser aerosol spectrometer (e.g.: LAP 322, LAP 323, LAP 340) for determination of particle size and concentration
