Choosing the Right Microwave Extraction System
Microwave-assisted extraction (MAE) accelerates the recovery of target compounds from solid samples through controlled microwave heating. Compared with conventional solvent extraction methods, it can significantly reduce extraction times and solvent consumption while improving sample preparation efficiency and reproducibility.
Milestone ETHOS X solutions cover laboratory analysis and solvent-free extraction of natural products, from compact labstations to higher-capacity processing systems.

How Does Solvent-Free Microwave Extraction Work?
Solvent-free microwave extraction (SFME) uses microwave energy to heat the moisture naturally present in botanical materials, releasing essential oils and other volatile compounds without adding organic solvents or water. The compounds are recovered through a controlled condensation process.
For laboratory applications, Milestone also offers microwave hydrodiffusion and gravity (MHG) configurations to extract flavours and other natural compounds, including pigments and flavonoids. The ETHOS X line extends solvent-free extraction to larger-scale natural-product processing.

Amélioration de l'efficacité de l'extraction par solvant
The process of sample preparation represents a critical yet often overlooked aspect of chromatographic analytical procedures. It is here that errors are most likely to occur. Surprisingly, many laboratories still rely on the antiquated Soxhlet method, a technique dating back to 1879.
In contrast, Microwave-Assisted Extraction (MAE) employs sealed vessels to elevate the extraction solvent temperature beyond its atmospheric boiling point. This strategic approach offers several advantages. Firstly, the heightened temperature significantly enhances the solubility of the target analyte, while concurrently reducing solvent viscosity. As a result, MAE achieves two pivotal goals: more efficient sample preparation and reduced extraction durations.
Furthermore, the microwave-assisted extraction method stands out for its selectivity, speed, and the superior precision and accuracy it imparts to analytical results when compared to alternative approaches.
Microwave-assisted solvent extraction finds application in a wide range of scenarios, including the removal of organic pollutants from environmental matrices, determination of fat content in food samples, elimination of contaminants from food products, and the extraction of additives from plastics.

High-quality extracts with a processus d'extraction verte
Pour répondre aux limites des techniques d'extraction conventionnelles, Milestone a développé la gamme ETHOS X pour l'extraction de produits naturels tels que les terpènes du cannabis et du houblon, et les huiles essentielles d'une large gamme de plantes. La famille ETHOS X tire parti du mécanisme unique de chauffage sélectif par micro-ondes. Le chauffage interne de l'eau à l'intérieur de l'échantillon distend ses cellules et entraîne la rupture des glandes et des réceptacles oléifères. Ce processus libère les terpènes qui sont ensuite entrainés avec la vapeur d’eau in situ de la plante.
Application : True Hopping
Pour améliorer l'efficacité de l'extraction des arômes de houblon dans le processus conventionnel de houblonnage à sec, Milestone a appliqué une nouvelle technique de houblonnage appelée True Hopping, qui utilise l'approche bien établie de l'extraction par micro-ondes sans solvant (SFME).
Ce processus permet de récupérer jusqu'à 95 % des terpènes de houblon ainsi que les acides alpha et permet aux brasseurs d'établir des profils d'arômes très houblonnés tout en utilisant jusqu'à 40 % de pellets de houblon en moins.
