MSPD enables the simultaneous extraction and clean-up of
analytes from solid samples with solid, semisolid and highly
viscous features [15,16]; it can also be used as an alternative
method to classical extraction [1,13,17]. This technique shows high
flexibility and selectivity due to the variety of combinations of
sorbents and elution solvents [18,19]. Because of its simplicity and
high throughput, MSPD has been widely used for extracting
pesticide residues from highly viscous samples
