摘要： The invention provides a method for standardising an infrared spectrometer based on spectral patterns of constituents of atmospheric air naturally occurring in the spectrometer. The invention also provides a spectrometer applying the method. The method selects a spectral pattern in a recorded spectrum and determines a wavelength dependent position value for a feature, such as the centre of the pattern. This value is compared to a reference value that may be obtained from a spectrum recorded by a master instrument, and a standardisation formula can be determined. The absorption peaks from CO 2 ( g )around 2350 cm -1 are preferred as the selected pattern. The method renders the use of reference samples unnecessary and allows for the standardisation to be performed simultaneously with the recording of a spectrum of a sample of interest.

摘要： A method of measuring colour changes, such as during a titration, by means of a colour resolution unit (8) decomposing the light of the surface of a sample from at least three colour components, and a device for measuring the signals emitted by each selected spectral interval, as well as by means of a device for evaluating the signals transmitted by the measuring device. According to the invention, a vectorial addition is performed of the signals identifying each selected spectral interval. The vectors matching the signals of the selected spectral intervals are substantially perpendicular to one another and consequently the signals emitted by selected spectral intervals are mutually independent. Then the colour change is measured by a measuring being performed of the vectorial change Id of the colour vector signal IO. As a result a quantitative measurement of the colour change is obtained, said measurement for instance being used for identifying colour changes. In this manner a colour change can be identified automatically and completely automatically.
