The gravimetric sampling of dust - Dustwatch
Webmethod when the dust was loosened from the sheet metal duct surface with the aid of a blade. The authors recommend the use of the gravimetric tape and the op-tical method for measuring the amount of dust in air ducts (Fransson et al., 1995). Fitzner et al. (2000) studied six sampling methods (Table 2). Four of the methods were applications of the Web2 = post-sampling weight of sample-containing filter (mg) B 1 = mean tare weight of blank filters (mg). B 2 = mean post-sampling weight of blank filters (mg) V = volume as sampled at the nominal flowrate (i.e., 1.7 L/min or 2.2 L/min) EVALUATION OF METHOD: 1. Bias: In respirable dust measurements, the bias in a sample is calculated relative to the sonnen battery chemistry
