In a recent study, scientists evaluated different microextraction methods using green analytical chemistry (GAC) metrics.

EuSP2024 | GSAC2024 — The 3rd European Sample Preparation Conference and 2nd Green and Sustainable Analytical Chemistry Conference will both take place from 15–18 September 2024 in Chania, Crete, Greece.

Microextraction using sustainable green solvents, followed by mass spectrometric analysis, comprise a combined approach that is still in its infancy.

This article explores how automation can enhance laboratory productivity and reduces errors in peptide mapping.

This installment examines a sample preparation survey, focusing on sample sizes, laboratory techniques used, automation, the use of solid-phase extraction (SPE) devices (cartridges, disks, plates, tips), SPE chemistries and selection criteria, and problems encountered in SPE.

In this column, a fast, simplified procedure for determining simple sugars in fruit juices is described.
