Electrical Ionizer and Wide-range Particle Spectrometer™ (WPS™)

The new Electrical Ionizer (Model 1090) shown on top of the new extended-range WPS™ (Model 1000XP) generates (+) and (-) ions by corona discharge for bi-polar aerosol charging and size analysis by electrical mobility. It eliminates the need for a source of ionizing radiation (Po-210 or Kr-85) traditionally used for the purpose. The new Model 1090 is a precision aerosol charger capable of generating measurement results nearly identical to those from a Po-210 radioactive ionizer.

The Wide-range Particle Spectrometer from MSP is a wide-range aerosol size spectrometer by combining laser light scattering with differential mobility analysis and condensation particle counting. The lower size limit of the WPS has now been extended from 10nm to 5nm for size distribution measurement from 5nm to 10,000nm in 120 particle-size channels. With computerized recipe control, the WPS™ is one of the most user-friendly instruments ever developed in the field of aerosol measurement.

The new extended range WPS is now the standard WPS design from MSP. It is also available as a factory-upgrade to an existing WPS. Please contact factory for details.

The Model 7400AD is a technologically advanced real-time fiber monitor that automatically detects and counts airborne fibers such as asbestos, mineral wool, advanced composites, ceramic and glass. Each 7400AD is factory-calibrated with traceability to NIOSH Method 7400 for asbestos fibers. The 7400AD ignores non-fibrous background particles using the proven principle of electric-field-induced fiber alignment and oscillation.

The 7400AD is the ideal means to check and verify worker safety during asbestos remediation and removal operations. With its fully charged battery pack, the 7400AD will operate unattended for eight hours and record the observed fiber data at regular intervals. If the fiber concentration exceeds a user-defined, pre-set level, an audible alarm sounds. Within the 7400AD is a filter from which one can obtain samples for later chemical or physical analysis, such as comparison with phase-contrast microscopy. The on-board, specialized software allows users to set a range of performance features to customize the operation.
