Advances in the area of sample preparation are significant and have been growing
significantly in recent years. This initial step of the analysis is essential and must be carried …

Sample preparation is an important step in chemical analysis. It is generally done to deal
with problems associated with the nature of the matrix, low analyte concentrations in real …

A series of new hydrophobic deep eutectic solvents (DESs), which are liquid at room
temperature and have high density (> 1.4 g mL− 1), were synthesized using …

Since their introduction by Philip G. Jessop and co-workers in 2005, switchable-
hydrophilicity solvents (SHS), have gained a wide acceptance among scientists working in …

Sample preparation has been recognized as a major step in the chemical analysis workflow.
As such, substantial efforts have been made in recent years to simplify the overall sample …

A novel approach for dispersive liquid-liquid microextraction based on the use of deep
eutectic solvent as a disperser was presented for the first time. The procedure was …
