    Abstract: An instrument for quantitative analysis includes two shutters, one of which prevents light from being introduced into a black box housing a cell holder from the outside through a port in which a cell may be placed in and taken out the black box, and the other of which prevents light from impinging on a photomultiplier tube which is in communication with the black box. The shutters are controlled by a control unit so that one of the shutters opens when the other closes. The instrument also includes detectors which detect whether or not the cell holder and the cell are disposed at predetermined positions, respectively. The detectors output signals to the control unit. The control unit controls an automatic pipetting device to restrict a sample from being introduced into the cell when both the cell holder and the cell are not disposed at the predetermined position.

    Abstract: A device for detecting a transmissivity of a substance utilizing a transmitted light value, which comprises a light emitting element and a photo detecting element. The light emitting element and the photo detecting element are spaced from each other at a predetermined distance so that a transmitted light value of a substance passing through the space is detected as an amount of light transmitted therethrough. The photo detecting element further comprises a photo oscillator circuit including the photo detecting element as one component thereof and outputs a signal having characteristics selected from a cycle and a frequency corresponding to the transmitted light value, and when the condition of a substance exceeds a predetermined reference level, such information is displayed at a display unit. Further, the device carries out a detecting and discriminating operation when a temperature of a substance is at a level lower than a maximum temperature at which each component of the detecting circuit will not work effectively.The device is also provided with a detecting unit in which the light emitting element and the photo detecting element are kept firmly in contact with each other, with a spacer placed therebetween, by an external force caused by a spring, to make the space provided therebetween constant regardless of any deformation of any component of the device caused by heat or aging.

    Abstract: An apparatus and method for spectrophotometric analysis of material in a moving process stream wherein the material is directed into an observation chamber within a sample cell and exposed to a radiation beam suitable for spectrophotometric purposes. A radiation source and a radiation detector are contained within a first compartment and a second compartment environmentally isolated from the first compartment and within which the sample cell is contained. Reflectors are positioned within the second compartment for receiving the radiation beam from the first compartment, directing the radiation beam through the sample cell and the material to be analyzed contained therein, and directing the radiation beam back into the second compartment and the radiation detector positioned therein. The second compartment maintains the environment therein within a range acceptable for radiation analysis of the material within the sample cell. Mirrors are positioned within the second compartment for diverting the radiation beam from passage through the material and for determining a reference spectrum within the same environment as the sample cell and directing the diverted beam to the radiation detector.

    Abstract: A photometer head having a housing for receiving and supporting small test volumes. The housing includes a recess and a plate for substantially covering the recess. A light transmitter and a light receiver having first and second end surfaces are mounted within the housing and project into the recess at locations substantially opposite one another to define a gap between the first and second end surfaces for retaining the small test volumes. A liquid applicator extends through an aperture in the housing to dispense droplets of liquid test volumes into the gap. The light transmitter directs optical energy at the droplets and the light receiver receives the transmitted energy.

    Abstract: A gas analyzer which utilizes an infrared beam which passes through or has emanated from a gas stream. The analyzer has a plurality of gas cells which contain gas of the type whose concentration is being measured in various concentrations and at various total pressures. A beam of energy is forwarded to the analyzer, and is passed selectively to the various cells. In one embodiment, the cells are mounted where a rotatable deflector can selectively deflect and receive the beam to and from two fixed beam segments so that sequential readings at an infrared detector can provide measurements of concentrations, and calibration. In another embodiment, the cells are selectively moved into the beam path. The beam is formed and forwarded by a Cassegrainean system or by a combination of reflectors including a retro-reflector. An infrared calibration beam which does not pass through the gas stream is utilized for calibration.
