mbw so2 Measurement with Low-Cost

The HS-GDT method was developed as a low cost and relatively simple method to accurately measure SO. 2. in wine while avoiding disturbances to a wine sample's equilibrium (Coelho et al. 2015). The method relies upon the use of a syringe to draw a sample of wine. A known volume of headspace (HS) is then created above the wine, the syringe is
