假药中物相鉴定检测方案(X射线衍射仪)

Terra Application Summary Phase Identification and quantification of counterfeit pharmaceuticals Recent advancements in the field of X-ray Diffraction now makeit possible to easily perform a rapid identification and quantifica-tion of counterfeit pharmaceutical materials. As with mostpharmaceutical materials， a unique x-ray diffraction pattern ispresented for the active ingredient. Thus， a counterfeit materialis easily and readily identified by not on the lack of the activeingredient x-ray diffraction pattern， but also the identification ofthe substitute material. Counterfeit pharmaceuticals are packaged andpresented in a convincing manner. The above showsboth the container as well as the individual pill analyzedbelow 33-311 Gypsum， syn=Ca_ 040L30 22423150225010620022251---249.151.-043 4601 3834 3068 2301 1534 767 0 10 .20 30 40 50 The red pattern represents the genuine sample， while the blue pattern shows thecounterfeit material. The major peaks in the blue sample are the peaks associatedwith gypsum. A slightly more complex counterfeit sample is presented below. In this case， thegenuine material (Viagra) is represented in red， while the counterfeit sample， inblue， shows the presence of three"filler"minerals， gypsum ，bassinite ， andDolomite (MgCO3)
