摘要： In a spectrophotometer, each of a plurality of source optical fibers is selectively receptive of source radiation and carries the radiation to a corresponding selected liquid sample cell. A corresponding return optical fiber returns transmitted radiation from the sample to a polychromator. For selecting a sample, a switching member holds exposed ends of the optical fibers on a circle coaxial with an axle for rotating to selected positions. Respective optical trains in the instrument direct radiation into and out of the selected pair of fibers. The diameter of a source aperture, the spacing of the aperture from the radiation source, and the source area define a source etendue. The optical fibers have a fiber etendue substantially the same as the source etendue.

摘要： An optical switch includes a primary optical fiber terminating in a primary window, and a plurality of secondary optical fibers each terminating in a secondary window facing in the same direction as and spaced laterally from the primary window. A primary lens on a primary axis has a focal point positioned on the axis at the central window. Each of a plurality of secondary lenses has an axis and a focal point positioned on such axis at a secondary window. The secondary axes are parallel to and equidistant from the primary axis. A retroreflector is spaced from the lenses oppositely from each window and has an optical axis centered parallel to the primary axis midway between the primary axis and any of the secondary fibers. A stepper motor rotates the retroreflector about the primary axis to each of a plurality of selected positions to provide optical switching for light transmission between the primary fiber and any selected secondary fiber.

摘要： Standardization is achieved for FTIR spectrometric instruments that effect an intrinsic distortion in spectral information, the distortion being associated with an aperture size. An idealized function of spectral line shape is specified. With a small calibration aperture, spectral data is obtained for a basic sample having known "true" spectral data, and standard spectral data also is obtained for a standard sample. With a larger, normal sized aperture, standard spectral data is obtained again for the calibration sample. A transformation factor, that is a function of this data and the standardized function, is applied to spectral data for test samples to effect standardized information. In another embodiment, the standard sample has known true spectral data, and the basic sample is omitted. In either case, the transformation factor is applied to the sample data in logarithm form, the antilogarithm of the result effects the standardized information.

摘要： A primary chromatographic system is operated with a standard sample at several temperatures to generate primary retention times which are fitted to a function to determine thermodynamic constants to relate the times to temperature. A target chromatographic system is operated with the standard sample to generate secondary retention times. The function is used with these times to determine and an effective column parameter for the target system. The function then is used with this parameter and the primary times to determine a pressure program. Further operation of the target system with a application sample and the pressure program effects standardized retention times. A particular searching technique is utilized to apply the function. A temperature calibration technique with a selected sample measures column temperature for the target system, and a validation is done on the target system.
