“…13, 14 This technique has been used to determine plasticizers, pharmaceuticals, pesticides and inorganic compounds in several matrices. [15][16][17][18] In DLLME, the extracting solvent is the main parameter to be defined for the optimization of the extracting procedure and its choice should be based on its density, extracting efficiency of the studied analytes and adequacy to the chosen analytical technique.…”

“…A fim de minimizar este problema, Andruch et al [55] propuseram a combinação entre um sistema de injeção sequencial de análise (SIA, do inglês Sequencial Injection Analysis) e a técnica de DLLME para a determinação de tiocianato em amostra de saliva empregando detector espectrofotométrico. Os resultados obtidos demonstram a eficiência do sistema proposto, sendo que a combinação SIA-DLLME apresentou LOD de 17,0 µg.L -1 , e o método convencional por DLLME apresentou LOD de 100,0 µg.L -1…”

“…A automação da DLLME deve ser uma tendência no futuro, atualmente poucos artigos relatam o desenvolvimento de um procedimento analítico utilizando DLLME on-line [55,56] .…”

“…Flow based methods can be recognized as a universal tool for automation of a wide variety of analytical procedures, including DLLME [18,19]. Recently, there have been several approaches suggested for the implementation of various DLLME modes in flow systems, based on microcolumn phase separation [20], in-syringe approach [21], coupling with flow-batch sequential injection [22] and stepwise injection [23] systems, as well as, magnetic stirring [24]. However, to the best of our knowledge, the automation of EA-DLLME has not been reported yet.…”
