Microwave Extraction

Sample preparation is a crucial factor to be improved to follow the evolutions of modern trace organic analysis instrumentation. Microwave assisted extraction (MAE) plays a key role in maximizing the efficiency of your sample preparation process.
Without microwave extraction, various operations performed on the sample during its preparation for instrumental analysis account for 60% of the analyst’s time and are responsible for 30 to 50% of error in trace organic analysis.
In addition to these problems average trace organic chemists uses three or more sample preparation techniques per sample just to produce an analytical result.

Microwave Extraction System for Environmental Laboratories

Determination of organic pollutants in environmental matrices is a common task for thousands of laboratories worldwide, as it leads to controlling and protecting our environment from high levels of contaminants. This analysis is often done to evaluate the effectiveness of a remediation process, to assess the contamination in waste, in waste landfills and for general environmental monitoring. 
Extraction of pollutants from solid matrices is often performed with techniques that limit the productivity and have high running costs. 
Milestone listened to the needs of environmental laboratory professionals by developing the ETHOS X with the fastEX-24 rotor, which allows for simultaneous extraction of 24 samples in 40 minutes with minimal solvent usage. By using large volume disposable glass vials, the fastEX-24 rotor simplifies handling and allows to achieve lower detection limits.

ETHOS X Essential Oils

Flavours & Fragrance Extraction

The analytical procedure for The analytical procedure for flavors and fragrances extraction from plants or spices comprises two steps: extraction by steam distillation or hydro-distillation, and analysis by GC or GC-MS. While the analysis step requires just few minutes, extraction takes several hours, using a standard procedure based on the Clevenger (1928 year!).
To address these limitations, Milestone has developed the new ETHOS X for the solvent-less extraction of natural products. It takes advantage of the unique microwave selective heating mechanism. The internal heating of the water within the sample distends its cells and leads to rupture of the glands and oleiferous receptacles. This process thus frees essential oil, and the flavors extracts is evaporated by the in-situ water of the plant material.

ETHOS X Cannabis Extraction

ETHOS X for fresh cannabis extraction

The ETHOS X is a perfect complement to any extraction technique as it selectively extracts the terpenes without compromising the subsequent cannabinoid extraction step. Most conventional extraction systems work on dry plant material, causing loss of some of the terpenes characteristics, while the ETHOS X provides fresh cannabis extraction ensuring most complete and representative terpene profile and maintaining its natural flavor and aroma.
The ETHOS X completes the microwave extraction process in only a few minutes without the use of solvent, providing high efficiency, reducing process costs and ensuring the strain-specific profile of the plant.

ETHOS X Fat Determination

Total Fat Determination in Foodstuffs

Traditional methods lead to the use of large amounts of solvents to remove fat from a sample matrix, resulting in low cost-effectiveness.
As an example, conventional fat extraction of pretreated cheese usually requires 3 hours and over 100 mL of solvent per sample. The standard fat extraction methods are not efficient in matter of cost and time, also exposing laboratory technicians to dangerous solvents.
To overcome these limitations, Milestone has developed a fast yet accurate microwave-based technology, which allows the chemist to carry out the simultaneous determination of fat content in 12 milk and milk products samples in just 90 minutes, with equivalent results of those obtained with reference techniques like Rose-Gottlieb method, Weibull-Stoldt or Schmid-Bondzynski-Ratzlaff method
