    Abstract: Methods and apparatus for article authentication include an exciting radiation generator that exposes an area of the article to exciting radiation, and at least two radiation detectors that detect emitted radiation from the area in a first band and in a second band that does not overlap the first band. The first band corresponds with a first emission sub-band of an emitting ion, and the second band corresponds with a second emission sub-band of the same emitting ion. A processing system calculates a comparison value that represents a mathematical relationship (e.g., a ratio) between a first intensity of the emitted radiation in the first band with a second intensity of the emitted radiation in the second band, and determines whether the comparison value compares favorably with an authentication parameter. When the comparison value compares favorably with the authentication parameter, the article is identified as being authentic.

    Abstract: The present invention may include methods and apparatus for the detection of explosives using near infrared or infrared spectroscopy to detect nitro or even carbonyl groups. Embodiments may include, at least one radiation emitter may emit at least one wavelength towards a target. At least one reflected wavelength may be generated after the wavelength collides with the target. A reflected wavelength may then be detected by at least one detector and analyzed with an analyzer.

    Abstract: After a liquid sample between a sample-holding platform 11 and a window plate 22 is measured, a window plate holder 23 is raised, and a head 14 is moved from a standby position into the gap between the window plate 22 and the sample-holding platform 11. Then, the window plate holder 23 is lowered so as to press the window plate 22 onto the head 14 until the head 14 touches the sample-holding platform 11 below. Then the head 14 is swung back to the original position, whereby a wipe material 40 fitted on the head 14 simultaneously wipes off the liquid sample from both the lower surface of the window plate 22 and the upper surface of the sample-holding platform 11. Pressing the arch springs 35 enables the wipe material 40 to be easily attached to or detached from the head 14.
