MSP's new Flow-Focusing Monodisperse Aerosol Generator™ (FMAG™) produces particles for extended operational periods of time. Some aerosol generators are prone to operational clogging; however the FMAG's novel approach circumvents clogging while producing small uniform aerosol particles, allowing investigators to focus on research and not equipment difficulties.

MSP’s new Model 1520 FMAG is an aerosol generator that produces an airborne suspension of monodisperse droplets or solid, dry aerosol particles. The FMAG uses a novel flow focusing effect to break up the liquid feed stream to create aerosol particles of a uniform size, 0.7 to 15 µm in diameter. This novel approach to aerosol particle generation is particularly useful in applications requiring instrument operation over extended periods of time.
Other aerosol generators often require the use of orifices not much larger than the size of the desired particles. Instruments using these small orifices for particle generation often encounter clogging problems, limiting the instrument’s useful operation time and disrupting the research work. The FMAG circumvents the clogging with its large 100 µm-diameter orifice and creative particle generation method, thus allowing investigators to focus on research for extended periods of time without worrying about equipment difficulties. Importantly, biological cells suspended in this manner are still viable, rather than being killed by the stress of the particle generation mechanism.
The FMAG can deliver a variety of solid and liquid particles of a uniform and accurately known particle size to accuracies better than ± 1%. The particles generated provide a laboratory with standard aerosols for calibrating droplet and aerosol particle sizing instruments such as laser particle counters and particle size spectrometers. The FMAG can also be used to generate known size particles at a known rate for laboratory experimentation, exposure studies and a variety of applications in other aerosol research disciplines.
The FMAG’s built-in corona aerosol neutralizer generates a bipolar charge of gaseous ions to neutralize any electrical charge that may be generated during the droplet and particle formation process. This important FMAG aerosol generator feature ensures that static electricity does not skew the experimental research results.
MSP’s FMAG was recently introduced at the 2015 European Aerosol Conference in Milan, Italy, and at the 34th Annual conference of the American Association for Aerosol Research (AAAR) in Minneapolis, MN.
