MOREIRA, J. L.; MARCOS, A. M.  and  BARROS, P.. Proficiency Test on Ftir Wine Analysis. Ciência Téc. Vitiv. [online]. 2002, vol.17, n.2, pp.41-51. ISSN 0254-0223.

The FTIR (Fourier Transform Infrared) technology has recently become one of the greatest improvements in the routine work of a wine analysis laboratory. In Portugal a workgroup of laboratories equipped with FTIR wine analysers has been created in order to optimise this methodology. One of the most important tasks of this workgroup was to carry out a proficiency test for FTIR analysers. This test consisted in the analysis of the same sample by all the participants, using a FTIR wine analyser provided with the same analytical calibration and using the same procedure. The results obtained presented good reproducibility in what the most relevant parameters are concerned. This proficiency test enables a more effective quality control of the FTIR results of each laboratory and became an important tool to detect several malfunctions in the equipments of the participants.
