Analytical chemistry has always been evolving towards techniques that are increasingly
simple and effective and that conform to green principles. Disposable pipette extraction …

Disposable pipette tips extraction consists of a solid‐phase extraction in which the sorbent is
poorly dispersed in a pipette tip, which allows a quick and dynamic contact between the …

Mass spectrometry has been the “gold standard” for drugs of abuse (DoA) analysis for many
decades because of the selectivity and sensitivity it affords. Recent progress in all aspects of …

The efficient sample preparation is fundamental in the bioanalysis. Application of solid-
phase extraction represents effective sample clean-up and allows final compatibility with …

The investigation of novel sample matrices in the forensic sciences offers several possible
advantages, such as allowing for results to be obtained in cases where common sample …

Molecularly imprinted polymers (MIPs) represent an advance in sample preparation
techniques due to their inherent functionalized cavities with great rebinding capacity …

Many pollutants are present at trace level in our environment, which are beyond the scope of
the detection by advance instruments too. Therefore, there is urgent need to develop …

As análises toxicológicas forenses caracterizam-se pela investigação de compostos de
interesse forense, em especial drogas de abuso, em diversas matrizes biológicas. As …

In this study, the hybrid material 3-n-propyl (3-methylpyridinium) silsesquioxane chloride
(Si3Py+ Cl−) was synthesized and investigated as a novel sorbent phase for the disposable …

Brazil is the third largest contributor to Green Analytical Chemistry, and there is significant
participation of toxicologists in the development and improvement of environmental …
