Abstract: A method for classifying a sample based upon a complete spectral analysis. The sample is illuminated with penetrating radiation and an initial complete spectral analysis is performed based on spectral resolution of resonant fluorescence lines emitted at the surface, or within the volume, of the sample. If the initial complete spectral analysis yields the composition of the sample to within acceptable limits, analysis values are output to the user. Otherwise, further analysis, informed by the results if the initial complete spectral analysis, is performed.

Abstract: A hand-held, self-contained x-ray fluorescence (XRF) analyzer (200) produces a small x-ray spot on a sample (604) to interrogate the elemental composition of a sample (604) region of millimeter-size characteristic dimension. The analyzer (200) includes an x-ray source for aiming an x-ray beam (304) toward a desired location on the sample (604). The analyzer (200) may include a digital camera (316) oriented toward the portion of the sample (604) that is, or would be, interrogated by the x-ray spot to facilitate aiming the analyzer (200). The analyzer may generate a reticule (908, 910) in a displayed image to indicate the portion of the sample (604) that is, or would be, illuminated by the x-ray beam (304). The analyzer (200) may include a detector collimator (1200) positioned along a light path between the spot and the detector (314). The analyzer (200) may include a chamber through which the beam (304) and the response signal (312) pass and a coupling for receiving an end of a purge gas tank (2502) for providing a purge gas to the chamber. The analyzer (200) may include a sensor operative to detect an amount of ambient gas present in the chamber. A calibration target (2200) and method (2300-2308) are disclosed for calibrating a location of a reticule in the analyzer (200).

Abstract: An analytical instrument (400, 500, 600) stores and/or reads information related to a sample (100, 904) in a contactless memory (102, 202, 422, 704, 706, 708, 802, 804, 806), such as a passive or active radio-frequency identification (RF-ID) tag. The information may include information about: composition of the sample, one or more analytical instruments (400, 500, 600) that were used to analyze the sample, operator(s) (902) who used the instrument(s) to analyze the sample, user-entered data about the sample (such as an origin of the sample) or a combination thereof or the like. The memory may be attached to the sample or to a container (300), in which the sample is stored or transported. One or more copies of such a memory may be loosely stored with the sample, such as with soil in a plastic bag or a rail car. When the memory is attached to, or stored with, the sample, the sample becomes essentially self- documenting. Information about the sample, such as its composition or origin, may be read by a contactless memory reader, such as an RF-ID reader. An analytical instrument (900) includes a contactless memory reader, such as an RF-ID reader. Each person (902) authorized to use the instrument carries a contactless memory (908), such as an RF-ID tag in an identification (ID) badge (906). The instrument (900) scans for a contactless memory (908) containing information identifying an authorized user (902) prior to performing an analysis or prior to operating in a predetermined mode, thus preventing unauthorized persons from operating the instrument (900) or from operating the instrument in an unauthorized mode. An analytical instrument (1000) may be docked in a stand (1002, 1200). The stand (1002, 1200) provides electrical power, cooling, gas to purge air from an analytical gap within the instrument and/or other supplies or services to the instrument (1000). The stand (1002, 1200) contains a contactless memory (1020, 1400), such as an RF-ID tag, which stores information about the supplies and/or services the stand (1002, 1200) is capable of providing to the instrument. The instrument (1000) reads the stand's contactless memory (1020, 1400) and automatically sets operational parameters of the instrument (1000) in accordance with the supplies and/or services the stand (1002, 1200) 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.

Abstract: Methods and apparatus for adapting the shaping time and/or other pulse processing parameters of an x-ray detector (114) in accordance with the elemental composition of a sample and/or energy resolving requirements. X-rays (104) are directed from a source (102) onto a sample (110) and the radiation (108) responsively emitted from the sample (e.g., fluoresced radiation characteristic of the sample's elemental composition) and detected by an x-ray detector (114) that generates pulses representative of the energy and intensity of the incident radiation. Based upon initial analysis of elemental composition, the shaping time and/or other pulse processing parameter (s) are set to optimize count rate subject to constraints of energy resolution in a spectral region of interest.
