摘要： A tube is attached inside a container and forms an inlet aperture. A transparent bulb is sealed over the end of the tube. A fiber optic probe is inserted into the tube and bulb. The fiber optic probe is connected to a fiber optic transmitter and receiver, which sends a beam of light down the probe. The beam of light reflects off the contents of the container and the reflected light is received by the fiber optic probe. The fiber optic transmitter and receiver compares the light intensity of the reflected light with the light intensity of the light beam. Changes in this radio indicate there has been a change in the contents of the container.

摘要： 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.

摘要： A spectrophotometric apparatus (10) utilizes a sample cell (14) to perform infrared spectrophotometric analysis on a moving process stream (11) containing, for example, polymer melt. Material to be analyzed flows between two closely spaced-apart crystals (40) in an observation chamber (42). Infrared radiation is transmitted from one side of the material through it to the other side. Crystals (40) are contained within threaded retainers (38) and (39) positioned in a bore. The retainers (38) and (39) can be moved towards and away from each other to vary the absorption rate of the material.
