New Technologies That Accelerate Persistent Organic Pollutant (POP) Sample Preparation

Despite best efforts in 2004 to ban their use, persistent organic pollutants (POPs) remain prevalent across the globe, including in soil. To protect human health, agricultural and environmental soil require careful investigation, but preparing samples for gas chromatography–mass spectrometry (GC–MS) analysis is time-consuming, and mostly done manually. Accelerated solvent extraction (ASE) has been the preferred preparation method for the past few decades, and while we have seen advancements, the method remains manual. Now, new technology offers parallel sample processing, combined extraction and evaporation, and automation—leading to faster analysis, reduced risk of error, and freed-up time for personnel.

From “Green” to “Sustainable” Sample Preparation in Omics Studies in the Natural Product Field: Case Studies Dealing with Cannabis sativa L.

Plant metabolomics requires that as many metabolites as possible are extracted to obtain a reliable picture of the sample under study. Therefore, sample preparation plays a crucial role. In recent years, several efforts have been made to improve the environmental friendliness of sample preparation, including in the plant sector. However, the environmental friendliness of a method cannot be evaluated without also considering its productivity and, more importantly, its analytical performance to ensure not only environmental friendliness but also the “sustainability” of sample preparation approaches.
