FTIR analysis of ash in wine

Abstract: Abstract. In a modern oenological laboratory determination of ash is a limiting factor regarding the speed of analysis, since functional FTIR analysis of ash are not common yet. Therefore 324 samples were analysed by FTIR spectroscopy on TDI Bacchus 3 as well as ISO 17025 accredited reference method (OIV-MA-AS2-04: R2009) in two duplicates. FTIR spectra and reference data were uploaded into software for the calibration development and validation performed. Already the original TDI calibration was ready to use,… Show more

“…The use of four wavelengths and a centred average proved to be the most efficient solution. The validation of the method provided good estimations values and, according to the authors, after enlargement of the data set the method could be applied on an industrial scale (Jug et al, 2017). In addition, several other chemical elements, like chloride and sulphate anions, are considered important quality markers of the wine.…”
