The Milestone Ethos X microwave extraction system (MAE) from Analytix is designed to overcome the limitations of lengthy methods which require large amounts of solvents.
Prior to analysis, the extraction of environmental samples such as soils requires solvent extraction. Contaminants such as PCBs, semivolatile organic compounds, and PAHs have traditionally been extracted using lengthy methods that also require large volumes of solvents.
The Milestone Ethos X microwave extraction system from Analytix can extract organic target compounds from soils in full compliance with EPA 3546 (100-115 °C and 50-150 psi). The system can process up to 24 samples and 30g of sample per vessel simultaneously, improving the limit of quantitation (LOQ) for analysis, and extracting more than 200 samples during an eight-hour workday. Potential problems of contamination, memory effects, and cleaning are eliminated by using disposable glass vials.
Handling is very easy, with the sample weighed directly into the vial. Hexane/acetone or dichloromethane/acetone (1:1) is added, and the vessel is loaded into the 24 place FastEX rotor that has contactless temperature control in all positions. After 10–20 min of microwave heating, the sample is ready to be filtered and analysed by GC or GCMS.
