“…One study used hair to analyse amphetamine-type stimulants [79] whilst another study [80] used liver samples to analyse barbiturates, and due to the complexity of dealing with these matrices, the sample preparation is more complex and is detailed in the articles. [64] showed that by changing the dimensional parameters of the hollow fibers it is possible to obtain a considerably shorter equilibrium time, mainly when complex biological matrices are used.…”

“…Apart from one study [56], all of them employed EME, which explains why the methods were shorter. Even though two other studies [69,80] [110]. One of the advantages of using EME is that it usually does not require sample pre-treatment [68,70,120,150,157].…”

Over the past three decades, many studies employing hollow-fiber liquid-phase microextraction (HF-LPME) bioanalytical methods have been published. The basic mechanism of extraction relies on the migration of the analytes through a liquid membrane sustained in the pores of the walls of a porous hollow fiber, and from there into an acceptor phase present in the lumen of the fiber. The mass transfer occurs by passive diffusion and it can be enhanced by using a carrier or applying an electrical potential across the phases. This type of extraction method presents many advantages over classical techniques, such as high preconcentration factor, clean extracts, and a green chemistry approach. Due to its advantages, and considering that no study systematically compiled the characteristics of the published methods in one single accessible source of information, the aim of this systematic review is to assess the data regarding bioanalytical methods, compile, and analyse the studies published until up to October of 2017. The data source used for the systematic review were Pubmed, Web of Science, and Science Direct, and 171 studies were included in the final review by two independent reviewers, resulting in a reliable and accessible source of information about bioanalytical methods employing HF-LPME.

“…Existe ainda a possibilidade da substituição dos solventes orgânicos por óleos essenciais ou óleos fixos de plantas, tornando, assim, a LPME uma técnica de extração livre de solvente orgânico (PEDERSEN-BJERGAARD e RASMUSSEN, 2004;MENCK, OLIVEIRA et al, 2012).…”

“…É sabido que o tempo de extração é um fator fundamental para a extração, porém estabelecemos o mínimo de tempo (5 min) em banho ultrassônico para realizar uma análise rápida. O aperfeiçoamento dessa técnica em nossos experimentos nos permitiu, assim, o processamento de várias amostras simultaneamente MENCK, OLIVEIRA et al, 2012).…”
