Electrical detection is used for the first time to achieve real-time operation of a low pressure cascade impactor. An instrument is developed using Berner type multijet low pressure impactor stages with minimum modification. The cut-sizes of the seven channel system range from 0.030 to 1.0 渭m....
not only the mass concentration of particles but also the distribution of fine particles that are considered as the most detrimental to the human health (Dockery et al. 93, Schwartz and Dockery 92).The Electrical Low Pressure Impactor (ELPI) is a particle size spectrometer designed at Tampere ...

Once the spinal cord is sufficiently exposed a moderate contusion injury was performed with a 200Kdyn force using the Infinite Horizon Spinal Cord Impactor (IH 0400) (Precision System and Instrumentation LLC, Fairfax Station, VA). The muscles and subcutaneous layers are then re-approximated and ...
There are also a few alternative technologies for submicron airborne particle measurement. SMPS+E substitutes CPC with a Faraday cup and an electrometer. It measures particle number concentrations in the size range of 0.8nm to 1.1μm. Electrical low pressure impactor (ELPI) employs aerosol corona ...
