Exploiting gas diffusion for non-invasive sampling in flow analysis: determination of ethanol in alcoholic beverages

A tubular gas diffusion PTFE membrane is exploited for non-invasive sampling in flow analysis, aiming to develop an improved spectrophotometric determination of ethanol in alcoholic beverages. The probe is immersed into the sample, allowing ethanol to diffuse through the membrane. It is collected in...
