<p>An apparatus (100) for grinding a sample of an organic material in a liquid comprises a housing (104) which defines a cylindrical grinding chamber for receiving the sample and the liquid. The grinding chamber has a cylindrical inner wall and a bottom wall. The apparatus further comprises grinding means comprising a stationary grinding means (126) component and a rotatable grinding means component (120), which grinding means are arranged at the bottom wall of the grinding chamber, the stationary grinding means component and the rotatable grinding means component being separated by a distance of 0.02-0.04 mm, and motor means (106) for rotating the rotatable grinding means component relative to the stationary grinding means component in a grinding operation. In the grinding operation, the organic material of the sample and the liquid is expelled in a liquid stream from the grinding means in a substantially vertical direction upwardly along the cylindrical inner wall of the grinding chamber, and the liquid stream is deflected by deflecting means (130) towards the centre of the cylindrical grinding chamber for recirculating the liquid and the organic material of the sample into engagement with the grinding means. A system for analyzing a sample of an organic material comprises, apart from the apparatus for grinding the sample (100), analyser (300) means for analyzing the content of the constituents of the liquid sample, and preferably further separator means (200) for separating the liquid sample from the extract or the emulsion.</p> |
