Multisyringe Flow Injection Potentialities for Hyphenation with Different Types of Separation Techniques

Abstract

The advantages of combining flow techniques with separation techniques are noteworthy. Flow-based methods are excellent tools for automating analytical procedures owing to their speed of analysis, reagent and sample saving ability, versatility, and inexpensive equipment. However, flow-based methods alone do not allow the separation of several analytes in a mixture. On the other hand, separation techniques (viz., chromatographic separations, capillary electrophoresis), widely used in analytical research due to high selectivity, require more expensive instrumentation. Thus, the combination of both techniques achieved the required selectivity with a more versatile, automated and, in some cases, low-cost methodology.

Multisyringe flow injection evidences interesting features with the utilization of the aforementioned combination of methods. Its potential for hyphenation with different separation techniques have been recently explored and are depicted in the present paper.
