摘要： A method for measuring moisture content in a biological material in an automated procedure is disclosed. The method comprises the step of: providing a reference database for a plurality of different material types with known moisture content. Further, a sample of biological material, such as chips of wood, pulp, grain, crop or sugar canes, are scanned with electromagnetic radiation of at least two different energy levels and the amount of radiation transmitted through the sample of the biological material is determined at said two energy levels. Subsequently, a material type in the reference database most resembling the biological material of the biological material of the sample is identified, and the moisture content of the sample of biological material is determined based on the identified material type and the determined amounts of radiation transmitted through the sample.

摘要： An apparatus and a method for X-ray fluorescence analysis of a mineral sample is disclosed. The apparatus comprises an X-ray source (2) for generating an X-ray beam to irradiate the mineral sample; at least one fluorescence detector (4,5) for measuring fluorescent radiation emitted by the mineral sample when irradiated by the X-ray beam; and a processing unit for providing an analysis of the mineral sample based on the measurements made by the at least one fluorescence detector (4,5). Further, the apparatus comprises a sample container (3) arranged to hold the mineral sample during the irradiation, wherein the sample container is arranged to provide at least two different irradiation paths through said mineral sample during irradiation. An advantage with this arrangement is that it enables analysis of elements having a wide range of atomic numbers in a single sample with improved reliability and accuracy. This results in maximized detectability for a wide range of elements, while reducing the number of samples that needs to be prepared. The present invention also leads to simplified sample preparation, and to a faster and more cost-efficient analysis. This makes the apparatus particularly useful for field use.

摘要： A method for detecting an anomaly in a biological material is disclosed, including the steps of: irradiating the biological material with electromagnetic radiation of at least two different energy levels; measuring the amount of radiation transmitted through the biological material; and determining, for each energy level, a transmission value. Before or after irradiation of the biological material, a reference material of a predetermined thickness is irradiated and the amount of radiation transmitted is determined. For each energy level, a transmission calibration reference value is determined and a calibrated transmission value is determined for the biological material and the calibration reference. A material value based on a relationship between the calibrated transmission value and the presence of an anomaly in the biological material is determined by comparing the determined and expected material values for the biological material.

摘要： A method and device for detecting and analyzing X-ray radiation with a detector unit which is placed in connection with the X-ray radiation. The detection unit is connected to a processing unit for processing the information which is received from the detection unit. The detection unit is placed directly in the radiation field of the X-ray radiation, and the detection unit is in the form of a matrix or a vector provided with one of more detector elements. The processing unit processes the information which is obtained from each detector element in the detection unit. In addition, a collimator is arranged in front of the detection unit, with the collimator being formed such that the radiation is reproduced substantially in dot form on the detector element.

摘要： The invention concerns a method and arrangement for measuring the bone mineral content in the skeleton in a body part, which is irradiated from one side with X-radiation which is detected on the opposite side of the body part. The X-radiation has two energy levels, the detected radiation is analyzed and the thickness of the body part is determined. The analysis takes account of the thickness of the body part and in order to calibrate the measuring process, a reference object of known composition is measured. The arrangement comprises: means (3) for generating X-radiation at two energy levels which means is disposed on one side (2a) of a casing (2) whose shape is adapted to that of the body part and which means is directed towards the latter. A radiation-detector matrix (4) disposed on the opposite side (2b) of the casing detects the X-radiation received. The distance-measuring devices (50 are coupled with an image and signal-processing unit (7) and are disposed inside the casing (2) on opposite sides of said body part. The image and signal-processing unit (7) is arranged such that the bone mineral content is determined by a combination of the signals recorded in the detector matrix (4) and the signals received from the distance-measuring devices (5) with respect to the measurement on the body part and the measurement on the reference object of known composition.
