Comparison of an Electronic Nose Based on Ultrafast Gas Chromatography, Comprehensive Two-Dimensional Gas Chromatography, and Sensory Evaluation for an Analysis of Type of Whisky

Table 6

Comparison of GC × GC-TOFMS e-nose based on Fast-GC and sensory analysis for whisky samples discrimination.

Type of analysis	Discrimination of whisky due to the type	Advantages	Disadvantages
GC × GC-TOFMS	Correct	It allows for precise examination of the composition of the matrix.	It is time-consuming and expensive.
E-nose based on Fast-GC	Correct	It allows for a partial analysis of the composition of the matrix. It is quick and relatively cheap. The software includes chemometric analysis.	It does not allow for precise examination of the composition of the matrix.
Sensory analysis	Incorrect	It allows for quality assessment due to consumer preferences. It is relatively cheap.	It is subjective and does not allow for discrimination of whisky based on the type.
