Enhancing Solvent Extraction Efficiency
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 green extraction process
To address the limitations of conventional extraction techniques, Milestone has developed the ETHOS X line for extraction of natural products such as terpenes from cannabis and hops, and essential oils from a wide range of botanicals. The ETHOS X family takes advantage of the unique microwave selective heating mechanism. The internal heating of water within the sample distends its cells and leads to rupturing of the glands and oleiferous receptacles. This process frees the terpenes which are then evaporated with the in-situ water of the botanical.
Application: True Hopping
To improve the hop flavor extraction efficiency of the conventional dry-hopping process, Milestone has applied a novel hopping technique called True Hopping, which uses the well-established solvent-free microwave extraction (SFME) approach.
This process succeeds in recovering up to 95% of hop terpenes and allows brewers to establish very hoppy flavor profiles while using up to 40% less hop pellets.
