摘要： A method for controlling the dispensation of a liquid volume sample when metering amounts of liquid by sucking into a tube, probe or tip a volume of a liquid to be displaced and ejecting the sample to a different vessel. According to the method the metering act is performed normally and the liquid to be metered is, displaced thereafter in a desired vessel. During the metering act and after a desired amount of liquid is sucked into the metering line, a supplementary suction step is performed wherefrom the success of the metering act can be deduced. The pressure function of the supplementary suction step is measured and this function is compared with a calibration function.

摘要： The present invention relates to photometers wherein light signals on different wavelengths are directed to samples and a light scattered from or penetrated through the sample is measured with a photodetector. Method provides a required filtered light signal for a photometer (4). The method comprises providing a source of white light by a pulsed flash light source (7) and filtering the light signal for providing signals on different wavelengths by using multiple filters (6) arranged on a perimeter of a rotary filter disk (5). At least one filtered light signal is led to at least one photometer (4). The filter disk (5) Is rotated continuously for passing successive filters (6) over the path of light from the flash light source (7) to the photometer (4) and the flash light source (7) is triggered when a filter (6) providing the required wavelength of light is on the path of light from the flash light source (7) to the photometer (4).
