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.
