Research output: Contribution to journalArticlepeer-review


A charge measurement device for measuring the net charge-to-mass ratio of airborne particles was developed and evaluated. The device involves collecting particles on a filter and measuring the electrostatic charge induced on the filter with an electrometer. The reliability of the device was tested by using electrostatic charges of known magnitude and polarity. The ability of the device to measure different levels of charges was also tested using different types of airborne particles, including com starch, sodium bicarbonate, positively-charged water spray, negatively-charged water spray, and uncharged water spray. Further, the device was used to measure the charge of airborne dust in a swine building. Test results showed good reproducibility.
