Abstract: In the quantitative analysis of a sample by computing constituents from optical absorptivity data at different wavelengths, optical absorptivity data values for selected nominal wavelengths are obtained by curvilinear interpolation from measured optical absorptivity data values obtained by use of narrow band width filters. The computed optical data values are utilized to compute percentage constituents by means of algorithms which may include one or more first or second derivatives.

Abstract: Apparatus for determining the content of moisture or other substance in a material by measuring its relative reflectance at two infrared wavelengths. A chopped radiation beam is produced by arranging a tuning fork such that an oscillating element alternatively moves first and second spaced optical bandpass filters having first and second passband wavelengths into position to intercept a beam of source radiation. The chopped beam is directed on the material being analyzed, and radiation reflected therefrom is applied to a radiation detector. The relative transmittances of the filters at their passband wavelengths are such that the radiation detector generates alternating pulses of equal amplitude for a material having a specified content of the substance. The tuning fork also includes a third filter of zero transmittance which periodically interrupts the beam of source radiation so that the detector provides a background signal which is used to correct the amplitudes of the alternating pulses. The alternating pulses are separated and applied to a ratio-determining circuit. The output from the detector is also applied a feedback circuit regulating the temperature of the detector.

Abstract: This monochromator is made up of a number of discrete narrow band interference filters mounted on a drum which rotates with respect to a light beam so that as the light beam passes through each of the filter the angle of incidence of the light beam changes with respect to the filter. Each of the filters is for a different normal wavelength of peak transmission so that spectral analysis of the light source can be obtained.

Abstract: A densitometer for use in quantitative analysis of spots on a thin layer chromographic plate includes a movable plate support to permit scanning of the plate by a head assembly positioned above the support. For reflectance mode operation the head assembly contains a source of visible light for illuminating the plate with light which is subsequently reflected by the plate back towards the head assembly. For transmittance mode operation a source of ultraviolet light is situated below the support. The support is provided with a frame portion for contacting only the peripheries of the plate and an opened portion aligned with the spotted areas of the plate such that the spotted areas of the plate may be exposed to light from below by the ultraviolet light source during transmittance mode operation. Exposure to ultraviolet light causes the spots on a properly prepared plate to fluoresce thus emitting visible light. In both operational modes the light from the plate is detected by a sensing means located in the head assembly. The active portion of the head assembly is vertically movable by means of a solenoid between an operational position adjacent the plate and a position remote therefrom. In order to prevent head damage, the active portion is automatically moved to its remote position when the power to the densitometer is removed. In order to eliminate output transients from the sensing means due to vertical movement of the head assembly, the sensing means is energized only when the head assembly is in the operational position. The sensing means circuitry drives a balance meter and incorporates a damping circuit which regulates the meter sensitivity to make the meter less sensitive at the peripheries of the meter range. The head positioning solenoid is provided with a high voltage transient pulse generating circuit to enhance the efficiency thereof. Spring-loaded plate hold-down means are provided to releasably secure the plate to the support and the head assembly is provided with a pointer extending therefrom to identify the spotted area being scanned.
