A hand-held, self-contained x-ray fluorescence (XRF) analyzer produces a small x-ray spot on a sample to interrogate the elemental composition of a sample region of millimeter-size characteristic dimension. The analyzer includes a collimator for aiming an x-ray beam toward a desired location on the sample and for determining the size of the spot produced on the sample. The analyzer may include a digital camera oriented toward the portion of the sample that is, or would be, interrogated by the x-ray spot to facilitate aiming the analyzer. The analyzer may generate a reticule in a displayed image to indicate the portion of the sample that is, or would be, illuminated by the x-ray beam. The analyzer may automatically annotate the image of the sample with text or graphics that contain information about the analyzed sample. The image may be stored in the hand -held analyzer or provided for external storage or display.

An analytical instrument may be docked in a stand. The stand provides electrical power, cooling, gas to purge air from an analytical gap within the instrument and/or other supplies or services to the instrument. The stand contains a contactless memory, such as an RF-ID tag, which stores information about the supplies and/or services the stand is capable of providing to the instrument. The instrument reads the stand's contactless memory and automatically sets operational parameters of the instrument in accordance with the supplies and/or services the stand is capable of providing. Thus, the instrument may automatically operate in an enhanced mode, such as at a higher x-ray beam power, as a result of being mounted in the stand.

A radiation shield and method for reducing ambient radiation levels at a distance from a surface irradiated by penetrating radiation emanating from an instrument substantially along a propagation axis. The shield attaches to an end of the instrument proximate to an irradiated surface and has a surface of attenuating material disposed with a component extending outward from the propagation axis of penetrating radiation and substantially adjacent to the irradiated surface.

Radiation shield for portable x-ray fluorescence instruments

A radiation shield and method for reducing ambient radiation levels at a distance from a surface irradiated by penetrating radiation emanating from an instrument. The shield attaches to an end of the instrument abutting an irradiated surface and has a platen of attenuating material disposed within a plane substantially transverse to the propagation direction of penetrating radiation and substantially adjacent to the irradiated surface.
