Developments in single-drop microextraction

Journal of Chromatography A, 2007
Single-drop microextraction (SDME) has become a very popular liquid-phase microextraction technique because it is inexpensive, easy to operate and nearly solvent-free. Essentially, SDME combines extraction (and conceivably, cleanup) and concentration in a minimum number of steps, and thereafter, direct extract introduction into an analytical system. In

Solid Phase Microextraction

2001
Solid Phase Microextraction (SPME) uses a small volume of sorbent dispersed typically on the surface of small fibres, to isolate and concentrate analytes from sample matrix. After contact with sample, analytes are absorbed or adsorbed by the fibre phase (depending on the nature of the coating) until an equilibrium is reached in the system.

Sol−Gel Capillary Microextraction

Analytical Chemistry, 2002
Sol-gel capillary microextraction (sol-gel CME) is introduced as a viable solventless extraction technique for the preconcentration of trace analytes. To our knowledge, this is the first report on the use of sol-gel-coated capillaries in analytical microextraction.

Solid-phase microextraction

TrAC Trends in Analytical Chemistry, 1999
Abstract In recent years, much attention in analytical chemistry has been paid to sample preparation techniques, especially those which minimise the consumption of organic solvents. One of the most promising of these, solid-phase microextraction (SPME), is presented in both its theoretical and practical aspects.

Green solvent microextraction

Nowadays, green analytical chemistry plays an important role in the field of analytical chemistry to minimize the use of solvents and other factors (e.g., time for preparation of each sample, sample volume, and solvent volume), which could increase damage and environmental impact.
