    Abstract: A small, portable, hand-sized apparatus for detecting microorganisms or chemicals in liquid samples by fluorescence polarization. The apparatus operates using a low power excitation light source, such as an LED, in order to irradiate a sample with polarized light. Detection of emitted polarized light from the sample is detected in multiple planes simultaneously using low power detectors resulting in an elimination of error caused by drifts in intensity in sequential measurements and in reducing assay time.

    Abstract: Disclosed herein is a device and methods for the rapid chemiluminescence assay of surfaces to detect the presence of microbial contamination. The device and methods are suitable for use by untrained personnel under the relatively harsh and variable conditions found in the field, for example in fast food restaurants and other food preparation areas. The chemiluminescence reaction that is the source of the analytical signal in the disclosed assay device and method is preferably based on a luciferase/luciferin system. The method for sampling disclosed herein comprises the steps of pre-wetting the sampling swab to a level below that of absorptive saturation; wiping a surface to be sampled with the swab with sufficient pressure to expel the wetting solution onto the surface; and, after reducing the pressure exerted on the sampling swab, further wiping the surface to re-absorb the moisture from the surface.

    Abstract: An apparatus for displaying chemical projects a chemical image of an object back onto that object. At region (23) light travels from the object to the apparatus (20) and back from the apparatus as it projects onto the object. Light (24) from the object (22) (which is illuminated by natural light) passes through an objective lens (31) of the apparatus. In its path is rotating mirror (25) and when the mirror is parallel to the path of the rays of light (24), the light is allowed to pass on to hyperspectral camera (26) which is of the AOTF type. The output from the camera is transmitted to processor (27) where the chemical image is generated from the hyperspectral data. The camera generates a series of monochromatic images that are passed to the processor and the chemical image is built up as the camera scans through the appropriate wavelengths. The image data is then transmitted to a projector (28) whose output image is focussed by lens (30) towards the rotating mirror (25). When the mirror is in the position illustrated, the image is reflected off the mirror and back through lens (31) to the imaged object (22).

    Abstract: A method determines an alcohol content of liquids that contain at least water and alcohol as well as sugar or similar substances, in the liquid. The liquid is located in an analysis cell is irradiated by an IR-LED light source, which emits infrared radiation with λ=1000-1500 nm. The IR light absorption is measured at least two different wavelengths, and the measurement values are converted into data on the alcohol content of the liquid. The liquid is irradiated with a first IR radiation with a wavelength λ1, where the absorption coefficient of the alcohol, and the absorption coefficient of the water, are identical in magnitude, and with at least a second IR radiation with a wavelength λ2, where the absorption coefficients and are different. The absorption measurement values determined by an IR detector are applied to a calculating unit for the calculation of the alcohol content.
