Abstract: A probe having a probe head in which is formed an opening for receiving a sample to be analyzed, the head comprising a pair of optical interfaces disposed at an opposing inner surface of the opening to delimit a path for optical radiation through the opening, wherein one of the pair of optical interfaces comprises a transparent element adapted to permit optical radiation in one or more wavelength regions of interest to travel between the probe head and the opening, the optical probe comprising a movable diaphragm in which one of the pair of optical interfaces is located for movement therewith and an actuator operably connected to the diaphragm to control its movement so as to vary the path length wherein the probe head comprises a hinge system cooperable with the actuator to move the optical interface in the movable diaphragm in an arc to vary the path length.

Abstract: An analyser (2) comprises a sample chamber (6) for holding a liquid sample containing particles and an ultrasound source (16) acoustically couplable to the sample chamber (6) to supply resonant ultrasound energy for acoustically concentrating particles in the liquid sample in nodal planes established thereby. A probe (12,14) is also provided which is adapted to supply electromagnetic energy into the sample chamber (6) and to receive the supplied electromagnetic energy from the sample chamber (6) at least during a time at which particles are substantially concentrated in associated nodal planes. The analyser (2) is provided with an analysis unit (28) in operable connection to a detector (12) of the optical probe (12,14) and is adapted to determine one or both a quantitative and a qualitative property of the liquid sample from the received electromagnetic energy.

Abstract: The present invention relates to a method of determining a constituent of a sample and more specifically, to a method of correcting an absorbance value for a spectrometer. The method is especially applicable in connection with spectrometric analysis instruments for quantitatively determining the chemical composition of fluids, e.g. the content of fat, protein, lactose or urea, in food products, especially in raw milk or dairy products. The method is based upon a measurement of one or more selected ranges of a spectrum, providing an absorption spectrum of the product. The method may be applicable in connection with all spectroscopic instruments giving rise to specific ranges of a spectrum, such as UV, VIS, NIR, IR, NMR, MS, etc.). Typically, the spectrum will be a MID-IR absorption spectrum.
