Abstract: An apparatus and related method for optical calibration of spectrophotometers is described. The apparatus is a calibration plate including one or more cuvettes filled with solutions of interest. The cuvettes are sealed to prevent evaporation. The cuvettes also possess a compressible component to allow for expansion of the solution and a bubble control apparatus to ensure that the compressible component does not intersect the beam path. A piece of neutral density glass is optionally included in the apparatus to track optical changes of the solutions over time.

Abstract: A for traceably determining an unknown optical path length of a sample in an optical measuring device comprises the steps of: providing a drop analyser connected to a standard spectrophotometer; providing a certified reference material contained in first and second closed high accuracy cuvettes; measuring absorbance of the certified reference material to obtain a first absorbance measurement for the first specified path length; measuring absorbance of the certified reference material for a second path length to obtain a second absorbance measurement; using a dropping device to drop a specified volume of the solvent on an optical surface so that the path length of the specified volume can be determined by reference to the first and second absorbance measurement; and using the dropping device to drop the same volume of sample as the specified volume of solvent on the optical measuring device.

Abstract: The invention relates to a gas analyzer for measuring the mercury content of a gas having an Hg light source which transmits transmitted light having wavelengths of at least one spectral line of the mercury, a measuring cell in which the gas to be measured is present, a light receiver, an evaluation unit and a test cuvette which can be introduced into the beam path for checking the operability. To provide an improved gas analyzer which can be calibrated in a simple manner as well as a corresponding improved calibration method, provision is made that the test cuvette contains benzol as a test gas.

Abstract: The embodiment of the pollution monitor described in the specification uses the principle of ultraviolet-induced fluorescence to detect and measure gaseous pollution in air, smokestack exhaust and other fluids. Improved calibration or standardization is effected by the use of one or more calibration cells in which a non-gaseous material simulates the fluorescence of the gaseous species under investigation, by scattering the incident ultraviolet light into a spectral region similar to that of the fluorescence of the gaseous species. Examples of suitable materials have been found to be aluminum, gold, platinum and molybdenum, all of which scatter light in the appropriate spectral region at a level which stays substantially constant with time.In the preferred embodiment, the sample cell and the calibration cells are all formed in a single cell block by drilling holes into solid bar material which holes function as the individual cell cavities. The sample cell has ports for the flow of sample gas therethrough, while in each of the calibration cells, the metallic material is mounted to intercept and scatter the incident ultraviolet light energy. The cell block is constructed to rotate so that the several cells can be individually aligned in the light path between the ultraviolet source and fluorescence detector.
