The company is a specialist in cascade impactor
technology with products serving the pharmaceutical and aerosol research markets, as well nano-particle generation and measurement technology serving the semiconductor device fabrication market.
The methods available for collecting fungal for this research are used biostage single-stage impactor viable cascade impactor
attached to a SKC Quick Take 30 are.
In combination with the BAC 2000, a timer-controlled solenoid valve used as part of the system for determining the APSD of PF Inhalation Powders, these accessories enable standard test equipment, including the Andersen Cascade Impactor
, to be tailored to meet the specifications of the new monographs.
Rapid check of cascade impactor
cut-sizes using a polydisperse challenge aerosol calibration method.
2009) and concur that the secondary sizing of particulate samples initially collected with a size-selective cascade impactor
and then resuspended in solution is useful information.
With the A-SRS and N-SRS, the analyst dismantles the cascade impactor
and places all components (including the induction port, mouthpiece adapter and collection plates/ cups) into their respective holders on the sample recovery bed.
Measurements were obtained in the plume above each appliance as in the earlier study using a personal cascade impactor
that determined particle sizes from 0.
In a cascade impactor
, particles are captured by inertial force.
The main particle sampling instrument, the personal cascade impactor
, and the same grease vapor sampling instrument, the EPA Method 5 sampling train, were used in this study so the results could be compared directly with the results obtained in ASHRAE RP-745.
Some samplers collected airborne particles in one filter substrate for total aerosol concentration, whereas other samplers housed a five-stage, high-volume cascade impactor
(model SA235, Andersen Instruments) for total concentration as well as particle size distribution.

CEN standard EN 13544-1 specifies the use of a multiple stage cascade impactor
to characterise the size of droplets produced during nebulisation.
