This protocol describes how to perform automated solid-phase microextraction (SPME) and thin-film microextraction (TFME) in a 96-well plate format for high-throughput analysis of drugs ...

Microextraction is a sample preparation technique to extract and preconcentrate analytes present in any given sample for analytical processes. Different sample preparation approaches for phytosterol ...

Microextraction technologies coupled with GS-MS and LC-MS are especially useful for quality control, such as in the study described above, as they can be applied to a diverse array of substances and ...

Researchers at the University of Caldas (Manizales, Caldas, Columbia) investigated the volatile organic compounds comprising the volatilome of Hass avocado peel, pulp, and seed grown in the northern ...

This is a 1-day special topics course on solid-phase microextraction (SPME) that will be held twice a year. SPME is a solvent-free sample preparation technique used for extracting volatile and ...

In the examples presented here, Custodion ® Coiled Microextraction (CME) syringes and the Torion T-9 ® Portable GC/MS were used to collect and identify fentanyl, acetyl fentanyl, carfentanil and ...

The thin-film microextraction (TFME) form of SPME further offers a higher surface area and coating volume, which enhances extraction efficiency without compromising extraction kinetics.

The German standard DIN 38 407-41 describes a method for the analysis of volatile compounds from aqueous samples by headspace-solid-phase microextraction (HS-SPME). Analytes are volatile, organic ...
