Abstract:
A compact, low-cost system for the detection of counterfeit or sub-potency pharmaceuticals is implemented by use of a low power X-ray source, an incident collimator containing a series of concentric, non-parallel slits, receiving collimators containing a series of concentric, non-parallel slits, additional collimators to limit tangential divergence and a single, near room temperature energy dispersive detector that sums the plurality of diffracted x-ray beams. In this system, the tradeoff between spectral resolving power and the diffracted intensity is eliminated. Also provided are methods to determine the optimal diffraction angle for a given test material, determine the instrument geometry and design parameters, and assess the system performance and sensitivity to alignment errors.

Claim (Index 21):
A method of identification of crystalline materials by X-ray diffraction, comprising:\n a. irradiating a crystalline material with a broad spectrum X-ray beam, the X-ray beam being emitted by an X-ray source in a system having a symmetry axis; b. collecting a plurality of incident X-ray beam by means of an incident beam collimator having a plurality of incident annular slits, each having incident annular slit having an apex, the incident beam collimator being concentric with and perpendicular to the system symmetry axis and each said incident annular slit having the X-ray source at its apex; c. collecting a plurality of diffracted X-ray beams by means of one or more diffracted beam collimators having a plurality of diffracted annular slits, the diffracted beam collimators being concentric with and perpendicular to the system symmetry axis, wherein the diffracted annular slits only permit passage of the diffracted X-ray beams that originate from a diffraction plane perpendicular to the system symmetry axis, wherein the diffraction plane comprises vertices of a plurality of irregular convex quadrilateral cross-sections, the cross-sections being formed where the incident X-ray beams and a projection of an acceptance angle intersect, the acceptance angle being formed by the one or more diffracted beam collimators; d. collecting and integrating the plurality of diffracted X-ray beams that pass through the diffracted beam collimators by means of a single energy dispersive X-ray detector; and e. comparing the X-ray diffraction pattern collected by the detector and matching said diffraction pattern to a library of known materials.
