    Abstract: The present invention relates to a method and apparatus for detecting transitions between different gas or liquid products in a flow path and, more particularly, it relates to an apparatus and method utilizing Raman spectroscopy for detecting transitions between petroleum products. A Raman spectrometer is preferably to produce a monochromatic excitation beam at a wavelength of approximately 670 nm. The spectrometer consists of an entrance slit, a combined diffraction grating/focussing element, and an exit slit. The Raman signal, which exits the spectrometer exit slit is detected by a highly sensitive photomultiplier tube, and sent to a computer device for data acquisition and analysis. The proposed invention detects liquid or gas products in a flow path by detecting the changes in the composition of various petroleum products flowing through a gasoline pipeline, by means of exposing samples of various petroleum products to the Raman spectrometer system.

    Abstract: For identifying black plastics effectively and rapidly, it is desirable to maintain full laser power while reducing the power density. This is achieved by the incorporation of a moving lens that disperses the 0.5mm laser spot over a larger area typically of about 5mm in diameter. The entire signal from the larger (5mm) diameter is collected at the same spot in the fiber bundle leading to a Raman or other spectral analyzer. There are no other modifications required for the rest of the system as the moving lens does not affect the collection efficiency of the characteristic signal from the sample.

    Abstract: Raman spectroscopy probe assemblies are disclosed for use with portable and/or handheld analyzers. The probes are also adaptable to sample liquids, and/or powders, tablets and/or other solids and are capable of withstanding harsh environmental conditions. The probes include an optical head assembly, associated optical fibers and replaceable sampling tubes. Safety shut-off mechanisms are provided to reduce the risk of inadvertent exposure to radiation. In one embodiment, the shut-off switch is a spring-biased shutter that is opened by a solenoid only under predefined proper operating conditions. In another aspect of the invention, a simple orthogonal optical head assembly is disclosed that does not require collinear optical paths. The orthogonal arrangement of input and captured light paths also reduces the need for precise alignment of the optical components. The orthogonal optical head assemblies of the present invention are well suited to accommodate the shutoff mechanisms of the present invention. The open architecture of the orthogonal assembly also facilitates the placement of lenses and/or filters within the head assembly, and also accommodates other elements, such as energy absorbing chambers, within the head assembly. In another aspect of the invention, sampling tubes, and replaceable end caps for such tubes, are disclosed that facilitate hand measurements of substances.
