Abstract:

Respirator Quantitative Fit Test RQFT Flame Photometer data have been compared with total particle volume calculated from LAS-X laser spectrometer particle count data. Total volume data were calculated by the method developed by Goldberg and Laird 1. Results indicate that there is a linear relationship between flame photometer voltage and the logarithm of sodium chloride NaCl total particle volume over 3-4 decades in NaCl concentration. Results also indicate that flame photometer voltage is not strongly dependent on NaCl particle size. Total particle volume data can be used to calibrate the flame photometer over about 4 decades in NaCl concentrations. Originator supplied keywords include Laser spectrometer, Flame photometer, Sodium chloride, Aerosols, Respirator quantitative fit test, RQFT.
