The Sample Processing Module with a standard split/splitless injection port, incorporating either a syringe through septum injection, or Auto Sampler delivers the sample to a Programmed Temperature Column Module (PTCM). The inlet includes septum purge to prevent bleed components from entering the system.
The PTCM is controlled by the method. It contains a 5% Carbowax 20M 80/120 Carboblack B Resistively Heated Stainless Steel Capillary Column and is operated in a temperature programmed mode. The column provides the separation of the hydrocarbons in the liquid extract. (See Figure 2).
Fusel alcohols are higher order alcohols and typically contribute to a hot, spicy, solvent-like flavor and an alcohol “burn.” Small amounts of these components may be desirable in some wines and spirits, but they can also be offensive and unwanted. In addition to their contribution to flavor, fusel oils can cause low carbonation and poor head retention in beers.
