The Potential of Automated Strategies in Microextraction Procedures Coupled to Chromatographic Techniques

Multiple-cumulative trapping headspace extraction coupled with high-concentration-capacity tools, such as SPME, enhances sensitivity of volatiles, as illustrated here in food analysis.

Multiple-Cumulative Trapping: A Fascinating Option to Enhance Headspace Profile 

Ionic liquids (IL) are a very versatile tool for natural product and food analysis. When combined with moieties with different functional groups, ILs can be tuned to obtain extraction media with different properties and selectivity.

Exploiting the Tunability and Versatility of Ionic Liquids as Extraction Phases for Targeted and Omics Studies in the Plant and Food Fields

We explore the aspects of sampling that are of highest importance in an analytical scheme. Devices and processes for obtaining appropriate samples outside of the laboratory are presented.


Putting the Sample into Sample Preparation

Understanding the fundamentals of extraction methodologies is critical, and can enable chromatographers to find smart solutions to tackle the complex composition of different types of samples.


Fundamentals: To Prep or Not to Prep? That is the Question...

We look at five modern treatments of chromatographic sample extraction, explaining their initial conception and development to shed light on their current roles as analytical tools.
