Sample Preparation

A recent intercontinental collaboration between two academic research laboratories—the Aristotle University of Thessaloniki, Greece, and the Florida International University, USA—has yielded a significant number of analytical/bioanalytical methods using fabric phase sorptive extraction (FPSE), magnet integrated fabric phase sorptive extraction (MI-FPSE), and capsule phase microextraction (CPME) for the isolation of various analytes from different complex sample matrices.

Continued development of needle-trap extraction (NTE) has expanded its versatility in applications such as disease diagnosis, aerosol-bound analytes, and breath analysis.

These questions tend to focus on dealing with octanol-water partition coefficients, as well as more practical applications of sample preparation.

Test your knowledge of octanol-water partition coefficients and practical applications of sample preparation.

Integrating electric fields into extraction techniques increases sensitivity and selectivity. These approaches are compatible with miniaturized, portable, and many biological samples.

A snapshot of key trends and developments in sample preparation according to selected panellists from the chromatography sector.

The differences between DIMS and GC approaches are presented.

As I write this, I’m also grading the final exam from my Chromatography and Separations course. Here’s your opportunity to test yourself; answers are provided.

Can you pass this test of chromatographic sample preparation concepts?

This method greatly facilitates the analysis of a large number of pesticides.

This month we interview Natalia Manousi, from the Laboratory of Analytical Chemistry at the Department of Chemistry of the Aristotle University of Thessaloniki in Thessaloniki, Greece, about her work in the development and application of novel sample preparation techniques.

The recruitment of young, talented entrepreneurs within academia and industry is needed to tackle many of the challenges that exist today and that will emerge tomorrow.

Given that sample preparation consumes over two thirds of analysis time, sample preparation becomes the bottleneck issue in analytical chemistry, resulting in the urgent necessity of developing accelerated sample preparation techniques.

Extraction-based sample preparation has been recognized as a significant step in separation science. To facilitate the extraction with better resolution, higher sensitivity, and lower detection limit, some new assistant approaches have been introduced, including electric field.
