Calibration testing of the jet filter as a respirable sampler.
This work was done to determine whether the jet filter can satisfactorily serve as a respirable sampler. Monodisperse polystyrene latex (PSL) spheres, crushed quartz particles, and hot-mix asphalt plant dust were used to calibrate the jet filter. The deposition characteristics for the sampler matched those specified by standards quite well for the PSL and the crushed quartz particles, i.e., those particles with optical and equivalent aerodynamic diameters near the same. The jet filter can meet its original design purpose - respirable sampling of radioactive aerosols. The sampler can also be used in gravimetric determinations by cutting the filter into two parts for weighing - the center portion with the non-respirable and the outer annulus with the respirable fraction.
