Advanced Microwave Extraction System for Environmental Laboratories
Microwave-assisted solvent extraction offers superior lab efficiency in the determination of organic pollutants with microwave green extraction technique. Typical applications include chlorinated pesticides, semi-volatile organics, PAHs, PCBs, chlorinated herbicides, phenols, organophosphorus pesticides, dioxins and furans
The ETHOS X procedure is straightforward: samples are poured into high capacity disposable glass vials with the appropriate solvent mixture, then placed in the Weflon vessel and sealed. The unique vessel design, combined with precise temperature control, allows for simultaneous extraction of many matrices, which improves the lab’s throughput. The precise contactless temperature sensor allows complete control of the extraction cycle in all places, and the dedicated user interface displays the temperature of all samples in real time. The 100-mL glass disposable vials may hold up to 30 g of sample, allowing for lower detection limits with less solvent volume. Furthermore, memory effects common with other technologies are removed, allowing even trace analysis of difficult species like dioxins to be completed faster.
Despite the development of novel extraction technologies in recent years, they have fallen short of meeting the objectives of environmental laboratories. By allowing the extraction of a high number of samples in a single workday, the ETHOS X with fastEX-24eT overcomes the productivity limits of other traditional techniques. Other technologies work by sequentially processing one sample at a time, resulting in lengthy extraction cycles. In about 40 minutes, the ETHOS X analyses 24 samples simultaneously and avoids cleaning steps by using disposable glass vials. The graph below shows how the Milestone ETHOS X, Sequential Pressurized Liquid Extraction, and Soxhlet compare in terms of usual daily production.
Environmental labs must have high data quality and reliability. Fast, accurate, and exact analysis is possible with the ETHOS X and the fastEX-24eT rotor. The vessels, when used in conjunction with the temperature sensor, allow many matrices to be processed at the same time, ensuring maximum extraction efficiency. Furthermore, the fastEX-24eT rotor’s unique design with high capacity disposable glass vials (100 mL) prevents cross contamination and memory effect, resulting in repeatable findings.
Several official methods, such as US EPA 3546, ASTM, and other national methods, explain the use of microwave closed-vessel technology to improve the extraction efficiency of organic contaminants. The typical extraction conditions are listed in Table 1. The ETHOS X with fastEX-24eT improves the extraction of water-insoluble or slightly water-soluble organic compounds from soils, clays, sediments, sludges, and solid wastes using microwave technology. In fact, chlorinated pesticides, semi-volatile organics, PAHs, PCBs, chlorinated herbicides, phenols, organophosphorus pesticides, dioxins, and furans may all be extracted using the ETHOS X with fastEX-24eT.
The highly competitive nature of the environmental analysis market necessitates the development of novel solutions that allow for shorter turnaround times. The ETHOS X with fastEX-24eT minimises overall analysis expenses by boosting productivity, with a throughput of 24 samples in under 40 minutes. Cut solvent volumes, fewer maintenance requirements, and the use of low-cost disposable glass vials lower the cost per sample, boosting your lab’s competitiveness and profitability.
In environmental laboratories, atomic spectroscopy examination of elements is a typical procedure. The ETHOS X allows for the digestion of environmental matrices such as soils, sediments, and wastewater in full conformity with official techniques such as those used by the US Environmental Protection Agency. A variety of alternatives are available to meet the laboratory’s needs.
