Fig. 1From: Multivariate analysis of energy dispersive X-ray diffraction data for the detection of illicit drugs in border controlEDXRD schematic. Schematic showing the EDXRD setup. The X-ray source is collimated and focused into a scattering volume at which the parcel or calibration sample is placed. Diffracted X-rays are detected by 20 CdZnTe detectors each positioned at a fixed angle of 5°Back to article page
