Abstract: A spectroscopy system is provided which is optimized for operation in the VUV region and capable of performing well in the DUV-NIR region. Additionally, the system incorporates an optical module which presents selectable sources and detectors optimized for use in the VUV and DUV-NIR. As well, the optical module provides common delivery and collection optics to enable measurements in both spectral regions to be collected using similar spot properties. The module also provides a means of quickly referencing measured data so as to ensure that highly repeatable results are achieved. The module further provides a controlled environment between the VUV source, sample chamber and VUV detector which acts to limit in a repeatable manner the absorption of VUV photons. The use of broad band data sets which encompass VUV wavelengths, in addition to the DUV-NIR wavelengths enables a greater variety of materials to be meaningfully characterized. Array based detection instrumentation may be exploited to permit the simultaneous collection of larger wavelength regions.

Abstract: Disclosed are photometric methods and devices for determining optical pathlength of liquid samples containing analytes dissolved or suspended in a solvent. The methods and devices rely on determining a relationship between the light absorption properties of the solvent and the optical pathlength of liquid samples containing the solvent. This relationship is used to establish the optical pathlength for samples containing an unknown concentration of analyte but having similar solvent composition. Further disclosed are methods and devices for determining the concentration of analyte in such samples where both the optical pathlength and the concentration of analyte are unknown. The methods and devices rely on separately determining, at different wavelengths of light, light absorption by the solvent and light absorption by the analyte. Light absorption by the analyte, together with the optical pathlength so determined, is used to calculate the concentration of the analyte. Devices for carrying out the methods particularly advantageously include vertical-beam photometers containing samples disposed within the wells of multi-assay plates, wherein the photometer is able to monitor light absorption of each sample at multiple wavelengths, including in the visible or UV-visible region of the spectrum, as well as in the near-infrared region of the electromagnetic spectrum. Novel photometer devices are described which automatically determine the concentration of analytes in such multi-assay plates directly without employing a standard curve.

Abstract: An optical path switch divides sample path radiation into a time series of alternating first polarized components and second polarized components. The first polarized components are transmitted along a first optical path and the second polarized components along a second optical path. A first gasless optical filter train filters the first polarized components to isolate at least a first wavelength band thereby generating first filtered radiation. A second gasless optical filter train filters the second polarized components to isolate at least a second wavelength band thereby generating second filtered radiation. A beam combiner combines the first and second filtered radiation to form a combined beam of radiation. A detector is disposed to monitor magnitude of at least a portion of the combined beam alternately at the first wavelength band and the second wavelength band as an indication of the concentration of the substance in the sample path.

Abstract: A multifunctional infrared spectrometer system has an interferometer which receives the infrared beam from a source and provides a modulated output beam on beam paths to multiple spatially separated infrared detectors. A multi-position mirror element mounted at a junction position receives the beam on a main beam path and directs it on branch beam paths to sample positions, with the beam then being directed on the branch beam path to one of the detectors. One of the branch beam paths may include a sample holder at the sample position which can index between a position at which a sample is analyzed, to a reference material position, to a pass-through position for calibration purposes. The multi-position mirror element may also be indexed to direct the beam on a branch path to a fiber optic cable which has a probe at the end of it which may be inserted in a sample fluid or powder to be analyzed, with the reflected light from the probe being directed back on an optical fiber cable to a detector at the spectrometer. The multi-position mirror element may be moved to a position at which the beam is directed on a beam path to and through an integrating sphere to a solid sample, with the reflected light from the sample being directed by the surfaces of the integrating sphere to a detector. A detector may be mounted to detect the light transmitted through the sample to obtain measurements of both reflected and transmitted infrared light at the sample.
