MODEL 5705 / 5706

SCANNING MOBILITY PARTICLE SIZER + ELECTROMETER

Sizing & counting the smallest sizes with highest precision

The GRIMM SMPS+E systems feature the Vienna-type DMA design (Winklmayr et al., 1991; Reischl et al., 1997), well known for highest size resolution and lowest particle diffusional losses – even for the smallest particles – with a Faraday Cup Electrometer (FCE) as detector. The SMPS+E systems include the GRIMM 5706 DMA controller and the GRIMM 5705 fast and low noise FCE and can be operated at aerosol inlet flow rates of 1 - 5 L/min and sheath flow rates of 3 - 20 L/min. GRIMM offers a flexible design of the Vienna-type DMA with three electrodes of different length to accommodate a variety of experimental needs. GRIMM’s unique FCE design applies a rinsing air flow around the insulator of the Faraday Cup to minimize effects of leakage currents due to internal particle contaminations. The instrument is optimized to reduce the effects of mechanical shocks and pressure differences, enabling the SMPS+E as a reference instrument for the calibration of nano particle counters.
