Claim:
1. An apparatus for presenting a slurry sample to an analyser, the apparatus comprising: an inlet for admitting a slurry sample flow, an optical measurement opening for co-operating with external measurement optics, and a stabilizer surface facing towards the measurement opening, the stabilizer surface being adapted to form from the slurry sample flow a thinner, stabilized sample flow along the stabilizer surface and adapted to present the stabilized sample flow for an optical measurement through said optical measurement opening with the external measurement optics, wherein, for performing the optical measurement, the external measurement optics are adapted to send, through the measurement opening, at least one focused laser pulse to induce a plasma in the stabilized sample flow on the stabilizer surface, and wherein the external measurement optics are adapted to receive, through the measurement opening, light emitted by the induced plasma for spectrum analysis.
