| 摘要 |
The invention concerns a device for the spectrometric assay of a liquid vinefication product (1) comprising an optical spectrometer (5) adapted to generate spectral information from the contents of a spectroscopic a sample cell (4); a data processor having access to a chemometric calibration (11) developed from a spectral database (12) linking optical spectral information to compounds of interest in the liquid vinefication product (1) and configured to process the same to generate an output result (13) indicative of the presence of one or more compounds of interest in the liquid vinefication product (1) characterized in that the device further comprises a freezer unit (3) adapted for freeze distillation of the liquid vinefication product (1) to generate a liquid distillate for analysis in the spectroscopic sample cell (4). |
