Abstract: First, monochromatic near infrared light in a wavelength range of 700 nm-1100 nm from the slit of the near infrared apparatus 1 is applied to a reference ceramic plate through the optical fiber 7 to measure a transmitted light intensity of the ceramic plate which is a reference material for spectrum measurement. Next, in place of the ceramic plate, the test tube 4 containing a liquid sample of which the temperature has been adjusted at a predetermined temperature by a water bath and the like is inserted into the housing portion 5. The transmitted light intensity of the liquid sample is then measured using the same procedure as above. A so-called near infrared absorption spectrum in which absorbance has been plotted against wavelengths is displayed on the screen of the computer 2. Information about each object characteristic is extracted from the spectrum data using a calibration equation.

Abstract: A multispectral imaging probe delivers a range of wavelengths of excitation light to a target and collects a range of expressed light wavelengths. The multispectral imaging probe is adapted for mobile use and use in confined spaces, and is sealed against the effects of hostile environments. The multispectral imaging probe comprises a housing that defines a sealed volume that is substantially sealed from the surrounding environment. A beam splitting device mounts within the sealed volume. Excitation light is directed to the beam splitting device, which directs the excitation light to a target. Expressed light from the target reaches the beam splitting device along a path coaxial with the path traveled by the excitation light from the beam splitting device to the target. The beam splitting device directs expressed light to a collection subsystem for delivery to a detector.

Abstract: An analytical instrument suitable for a use in a variety of industrial environments features a housing having a sealed primary chamber filled with a dry, inert gas at a first static pressure. An instrumentation system is disposed within the primary chamber, where fire hazard is eliminated by the inert gas. The housing additionally includes a reference chamber holding a gas a second pressure lower than the first pressure. One or more pressure switches, in pressure-sensing relationship with both chambers, is operative to interrupt the application of power to the instrumentation system if the differential between first and second pressures falls below a predetermined value. In this manner, the instrumentation system is rendered safe whenever the primary chamber is breached or otherwise loses inert gas pressure.
