What is Confirm of the optimum detection angles of several substances using energy dispersive X-ray diffraction about?

Energy dispersive X-ray diffraction (EDXRD) is proposed as a suitable non-destructive method to rapidly identify substance. In this study, 4 samples (i.e., methamphetamine, TNT, sugar and salt) have been investigated using EDXRD at different scattering angle for 300 second. The measured peak positions of EDXRD profiles can be regarded as a 'fingerprint' of the substance. The aim is to find out the optimum detection angle and provide a simple and practical solution to rapidly confirm substance. Furthermore, the data collected of all kinds of substances could be taken a series of process in computer to consist data base, such as Background Deduction, Feature Extraction. On that basis, the automatic, instant and accurate detection substance could be achieved in the near future.
