S. standards for health-related dust measurements at the workplace: the respirable, the thoracic, and the inhalable fraction. We developed a novel instrument for personal, time-resolved concentration monitoring and sampling of these three fractions. The instrument combines intertial classification, filter sampling, and photometric aerosol detection.enaerosolphotometrydust615610620540journal article
