Abstract: In some aspects, a device for apportioning granular samples includes a sample feeder defining a conduit, the conduit including a first opening to receive the granular samples and a second opening. The device includes a shuttle operably coupled to the sample feeder to receive the granular samples from the conduit via the second opening. The shuttle is configured to apportion the granular samples to incrementally enter a sample chamber to be analyzed. The device includes an outlet conduit fluidly coupled to the sample chamber and configured to permit the sample chamber to be evacuated.

Abstract: A spectroscopic measurement apparatus 1A comprises an integrating sphere 20 in which a sample S is located, a spectroscopic analyzer 30 dispersing the light to be measured from the sample S and obtaining a wavelength spectrum, and a data analyzer 50. The analyzer 50 includes an object range setting section which sets a first object range corresponding to excitation light and a second object range corresponding to light emission from the sample S in a wavelength spectrum, and a sample information analyzing section which determines a luminescence quantum yield of the sample S, determines a measurement value ¦ 0 of the luminescence quantum yield from results of a reference measurement and a sample measurement, and determines, by using factors ², ³ regarding stray light in the reference measurement, an analysis value ¦ of the luminescence quantum yield with the effect of stray light reduced by ¦ = ²¦ 0 +³. This realizes a spectroscopic measurement apparatus, a measurement method, and a measurement program which can reduce the effect of stray light generated in a spectrometer.

Abstract: The invention relates to a cuvette comprising at least one insert having two measuring surfaces. Said insert is a test prod that has both measuring surfaces on one end that is at a distance from the other end of the test prod, and comprises an adapter for inserting into the cuvette shaft of an optical measuring device and insert and adapter means for detachably maintaining the at least one insert in the adapter, the measuring surfaces being at a distance from each other in order to position a sample between the measuring surfaces in a beam path of the optical measuring device, said beam path passing through the cuvette shaft.

Abstract: This invention permits to validate the measures registered by a hyperspectral measuring system, by means of at least one Reference made by a mosaic of pieces of different colours arranged ahead the item to be measured. In this way, during measurement, the system registers first the Reference, having known certified spectral values, then the item and, if required, when coming back, the Reference again, so as to register the error of measurement and/or even correct the spectrometric values of the sample.

Abstract: An auto-tracking spectrophotometer has a moveable look-ahead sensor for scanning at least a portion of a color matrix. The look-ahead sensor finds a portion of the color matrix for measurement by an optical system. The optical system for measuring the color matrix is then guided using the information provided by the look-ahead sensor.
