DiLLME: Dispersive Liquid-Liquid Microextraction Compendium

Martin Perkins

25th September 2019


Dispersive Liquid-Liquid MicroExtraction – DiLLME Applications are for analytical chemists who are reliant upon traditional, manual, liquid-liquid extraction to prepare samples prior to analysis and are dissatisfied with the errors, inconvenience, costs and risks associated with a 150-year-old technology.

DiLLME is a solvent extraction technique that utilises an organic solvent as a dispersing agent in combination with an extraction solvent (usually a chlorinated solvent such as dichloromethane), to aid in recovery and extraction time. Samples are mixed with this solvent mixture to form an emulsion before centrifugation to separate the extraction solvent ready for injection into the GC.

This document contains abstracts on four separate DiLLME applications and links through to the full notes, should you find them compelling.

Anatune Application Notes:

Anatune (and our partners) regularly produce Application Notes. These cover a wide and diverse range of methods, techniques, applications, and related chromatography technology. Our Application Notes provide detailed technical information, unique applications insight and method development & validation, as well as systems configuration innovations to ensure readers can further their knowledge in an engaging way. For many years, Anatune’s Application Notes have helped and supported analytical chemists in the fields of Gas Chromatography – GC, Liquid Chromatography – LC, and Mass Spectrometry – MS achieve to develop analytical solutions. Visit our Applications Note page to search for the insight you need in the following categories: Matrix, Technique, Analyte, Instruments, Product, Industry. Or alternatively, CONTACT US for more information or to put forward an Application Note subject and our Applications Team will be happy to support you in any way they can.
