Optimization of the Extraction of the Volatile Fraction from Honey Samples by SPME-GC-MS, Experimental Design, and Multivariate Target Functions

Figure 1

Evaluation of the optimal amount of sample in SPME GC-MS analysis: areas (-axis) of each peak identified by its elution time (-axis) using the experimental conditions reported in Section 4.1. Circles are represented on a color scale: the darker the circle, the larger the amount of honey. An enlargement is provided for the region of elution time between 15 and 40 minutes due to scale effects.
