Sample Preparation

This article outlines the relevance of extraction techniques, including exhaustive and non-exhaustive ones, in onsite strategies.

Headspace-solid-phase microextraction (HS-SPME) is widely used for the analysis of volatile compounds from different kinds of samples.

Passive samplers come in many forms and can be used in various fields. Here, we review multiple advances made to this sampling strategy.

Vacuum-assisted headspace solid-phase microextraction (Vac-HS-SPME) is quickly becoming popular for enhancing the extraction of semi-volatile compounds.

Daniel Wolbrecht, senior technical sales consultant at Anton Paar, held a workshop at the Gulf Coast Conference in Galveston, Texas, focusing on how heated autosampler units can help analyze difficult samples.

In this article, the author reports the results from a survey of trends in sample preparation techniques.

The Green Analytical Chemistry Workshop (1st TGAC) will be held 5–6 February 2024, at Novotel Paris-Charenton, Paris, France.

Núria Fontanals, Senior Researcher in the Analytical and Organic Chemistry Department at the Universitat Rovira i Virgili, outlines the benefits of passive sampling in liquids and how the approach can evolve in the future.

Scientists from Dalian Maritime University in Dalian, China, are testing a new amphetamine-type stimulant extraction system on wastewater and urine samples.

A team of scientists from Universitat Rovira i Virgili in Tarragona, Spain, is investigating a new method for testing water samples for contaminants of emerging concern.

Scientists based out of Zhejiang Academy of Agricultural Sciences in Hangzhou, China, recently used a new QuEChERS method for analyzing pesticides in fruit samples.
