What is Optimization of solid phase microextraction analysis of aroma compounds in a Portuguese muscatel wine must about?

## Abstract The fundamental suitability of solid‐phase microextraction (SPME) has been investigated for the quantitative determination of eight aroma compounds present in a Portuguese muscatel wine must. The method has been optimized using a commercially available fiber coated with 85 μm polyacrylate (PA). The matrix effect was evaluated by comparing the results obtained with the standard additions method to those obtained, for the same analyte, by means of a calibration curve (internal standard method). The results obtained with the standard additions method show poor accuracy and higher confidence limits than those obtained by the calibration curve. Experiments during the SPME process were carried out to investigate the influence of (1) ethanol concentration and (2) high concentrations of one analyte on the absorption of minor components. No significant decrease in peak response was observed either for ethanol concentration from 3 to 12% or for excess concentration of one analyte over the others. The method was evaluated with respect to the linearity, within run precision and limit of detection. The curves obtained by plotting mass ratio vs. area ratio showed higher correlation c
