Sponge-nested polymer monolith sorptive extraction

Journal of Chromatography A, 2023
Polymer monoliths are an alternative to traditional particle-packed supports used in solid-phase extraction because of their ease of preparation, high porosity, and pH stability. They often required the attachment of monoliths to a support, such as the internal walls of a column to enable their use for sample preparation.

Sorptive sample preparation – a review

Analytical and Bioanalytical Chemistry, 2002
Most sample-enrichment procedures currently available rely on adsorption of the analytes of interest by a suitable adsorbent material. Although good performance can be obtained for many practical problems, in some cases the applicability of adsorptive sample preparation falls short, particularly for the enrichment of polar and/or high-molecular-weight ...

Stir bar sorptive extraction (SBSE) e head space sorptive extraction (HSSE)

2014
La microestrazione in fase solida (SPME), introdotta nella seconda meta degli anni Novanta del secolo scorso, ha rivoluzionato le tecniche di estrazione e si e diffusa rapidamente grazie alla semplicita di utilizzo e alle ottime prestazioni (vedi cap. 7).
