In situ testing of tandem HEPA filter installations with a laser single particle spectrometer system
Conference
·
OSTI ID:6698870
System components and methodology for in place testing of tandem HEPA filters are described. The system consists of a very high volume thermal DOP generator for producing sufficient challenge aerosol, a single particle intra-cavity laser particle spectrometer for high sensitivity detection, a forward light scattering photometer to measure challenge aerosol concentration, and a diluter to interface the spectrometer and photometer measurements. Results of the measurements on 11 tandem HEPA installations are presented along with problem areas and recommendations for future work.
