Methods and systems for determining contamination in a petroleum-based sample, including irradiating the petroleum-based sample with a light beam from a light source such that a fluorescence signal is generated, guiding, by a mirror, the fluorescence signal to a gear-less rotating diffraction grating, the gear-less rotating diffraction grating spatially separating a fluorescence wavelength from the florescence signal, detecting, by an optical detector, fluorescence wavelength, transforming the fluorescence wavelength into a spectral contour diagram, the spectral contour diagram comprising a fluorescence wavelength variation over time, and determining, the contamination in the petroleum-based sample using the spectral contour diagram.

A motorized multi-cuvette rotatable carousel positions cuvettes around a stationary axis. A rotatable cuvette holder plate positions cuvettes in the carousel. The cuvette holder plate has spring tensioning elements that hold cuvettes in a precise position within the cuvette holder plate. A cuvette positioning arm is attached to the rotatable carousel assembly. The positioning arm geometrically positions the cuvette for depth-resolved laser-induced fluorescence testing.

Multi-cuvette autosampler for photo-optical measurements

A diagnostic composition to detect antibodies in a sample obtained from an animal or human being infected by, comprising at least one peptide containing a series of amino acids that form a continuous or discontinuous epitope recognized by sera from pigs infected with
