摘要: A gas analysis probe (60, 70, 74, 78) or probe (60, 70, 74, 78) for gas analysis is disclosed which is for or is used or provided in a pipe through which sample gas (S) flows. The probe (60, 70, 74, 78) includes a tubular member (61) and one or more sample gas inflow portions (65). The tubular member (61) is disposed to cross a flow of the sample gas (S), and includes a measurement field (69) to which the sample gas (S) is introduced. The one or more sample gas inflow portions (65) are provided in the tubular member (61). The sample gas (S) flows around and flows into the measurement field (69) through the one or more sample gas inflow portions (65).

摘要: A sample testing apparatus is disclosed for use in optical transmission analysis of fluid samples such as oils or engine oils. The apparatus comprises a transmission cell comprising first and second fixed walls (1,2) and a movable window (3) that is moved with respect to the first and second walls in and out of a test region (6), defining an optical path through a fluid sample with a portion extending through the or each gap (L1,L2) between the walls (1,2) and at least a portion of the movable window (3). The window may be stepped or continuously varying in thickness for linear movement. There may be more than one window mounted on a carrier of differing thicknesses, including rotational movement such as using as an impeller.

摘要: A system for detecting contamination of a window 18 of an optical system includes a polarizing beamsplitter 14, a quarter waveplate 16, a photodetector 12, and a processor 24. The polarizing beamsplitter is configured to receive a laser beam having a first polarization and reflect the laser beam having the first polarization to the window. The photodetector is configured to sense a magnitude of reflections of the laser beam from the window having a second polarization, wherein the polarizing beamsplitter passes the reflections of the laser beam from the window having the second polarization to the photodetector. The processor is configured to determine a contamination level of the window based upon the magnitude of the reflections of the laser beam from the window.

摘要: A nephelometric turbidimeter for measuring a turbidity of a liquid sample in a sample cuvette. The nephelometric turbidimeter includes a measurement light source configured to emit an axial parallel light beam directed to the sample cuvette, a scattering light detector arranged to receive a scattered light from the sample cuvette, and a diffuser comprising a diffuser body and a diffuser actuator. The diffuser actuator is configured to move the diffuser body between a parking position in which the diffuser body does not interfere with the axial parallel light beam and a test position where the diffuser body is arranged between the measurement light source and the sample cuvette so that the diffuser body interferes with the axial parallel light beam and generates a diffuse test light entering the sample cuvette.

摘要: Methods of obtaining or maintaining optical transference into deaerated liquid in contact with a light transference medium are disclosed. The methods comprise contacting a liquid chemical agent to a wetted surface of a light transference medium. The liquid chemical agent is selected from an acid, a chelant, a reducing agent, or combinations thereof, for a period of time and at a concentration sufficient to clean the wetted surface of the light transference medium. The methods may further comprise applying ultrasonic energy at a wavelength (λ) into deaerated liquid in contact with a light transference medium.
