St. Chow et al., THE HOMOGENIZATION OF ILLICIT HEROIN SAMPLES - AN EMPIRICAL AND STATISTICAL APPROACH, Journal of forensic sciences, 38(4), 1993, pp. 885-893
Although methods for sampling and testing illicit heroin are well know
n, a method for the homogenization of a heroin sample has not been sta
tistically established. This paper reports the conditions for homogeni
zing granular or powdery illicit heroin samples using a blender. The e
xperimental results and statistical analysis show that the homogenizat
ion of illicit heroin containing various concentrations of diamorphine
can be achieved after blending for three min.
