摘要:
An opto-mechanical apparatus including a hollow housing member having a first end and a second end, the housing member having a longitudinal axis, a parabolic mirror positioned on a side of to the first end of the housing member, and a mirror adjustment mechanism attached to the second end of the housing member, the mirror adjustment mechanism connected to the parabolic mirror through the housing member, the mirror adjustment mechanism configured to adjust an axial position of the parabolic mirror along the longitudinal axis and to adjust a radial position of the parabolic mirror about the longitudinal axis.
摘要:
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.
摘要:
A diagnostic composition to detect antibodies in a sample obtained from an animal or human being infected by Trichinella, 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 Trichinella.

摘要:
Container for receiving lab samples, whereby the samples are held in the container at a distance from the internal wall and in a defined height range, and whereby a drying device is provided inside the container at least in said height range and surrounds the sample on the side, at least partially, and includes a drying agent, and is constructed such that gas exchange between sample and drying agent is feasible.
