Experimental testing of the author's previously derived equation for evaluation of anisokinetic sampling errors, using talc and flyash of particle sizes 1-20 [mu]m as well as three types of dusts emitted from furnaces, produced a new equation which is valid for Stokes numbers 0.1-30, viz., C[sub s]/C[sub 0] = [alpha](V[sub 0]/V[sub s]) + (1 [minus] [alpha]), where C[sub s] and C[sub 0] are the concentrations with anisokinetic and isokinetic sampling, respectively, V[sub 0] and V[sub s] are the gas rate and the suction velocity, respectively, and [alpha] is an inertia function which is determined by the Stokes number, V[sub 0]/V[sub s], and a coefficient A[sub 0] which, latter, is approximately unity for fine particles and 0.0625 for coarse particles.
