MILESTONE H E L P I N G C H E M I S T S SUPERIOR LAB EFFICIENCY IN DETERMINATION OF ORGANIC POLLUTANTS ETHOS X Advanced Microwave Extraction System for Environmental Applications ETHOS X DESIGNED BY YOU SIMPLE HANDLING DEVELOPED FOR YOU 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 HIGH monitoring. Therefore, every day environmental THROUGHPUT laboratories deal with several challenges to ensure high quality data and fast turnaround time while maintaining their competitiveness. 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 SUPERIOR RETURN solvent usage. By using large volume disposable glass ON INVESTMENT vials, the fastEX-24 rotor simplifies handling and allows to achieve lower detection limits. CONSISTENCY & REPRODUCIBILITY SAFETY AND RELIABILITY MICROWAVE-ASSISTED EXTRACTION Solvent extraction is the least evolved and one of the most error-prone steps in pollutant analysis. Many laboratories still use the Soxhlet method that was developed in 1879! Microwave-assisted extraction combined with closed vessels, heats the extraction solvent above its atmospheric boiling point. The elevated temperature of the solvent increases the solubility of the analytes of interest, leading to a dramatic reduction of extraction time. Microwave extraction is faster and produces more accurate and precise results than other methods. Typical applications of microwave-assisted solvent extraction include chlorinated pesticides, semi-volatile organics, PAHs, PCBs, chlorinated herbicides, phenols, organophosphorus pesticides, dioxins and furans. When determining organic pollutants, most HIGHER PRODUCTIVITY environmental labs aim to improve productivity and lower detection limits with easy-to-implement solution. AT LOWER COST The sample preparation technique plays a pivotal role in overcoming this challenge. FOR GREATER ROI EASE OF USE WITH DISPOSABLE GLASS VIALS The ETHOS X operation is simple: samples are loaded into large volume disposable glass vials (1) with appropriate solvent mixture (2), placed into the Weflon vessel (3) and sealed (4). The unique Weflon material ensures homogeneous heating in all vessels, therefore increasing extraction efficiency even when different matrices are processed simultaneously, which enhances the lab's workflow. The accurate contactless temperature sensor ensures full control of 1 2 the extraction cycle in all positions and displays real-time the temperature of all samples on the dedicated user interface. The 100-mL glass disposable vials accommodate large sample amounts of up to 30 g, enabling lower detection limits with minimal solvent volume. In addition, the memory effects often observed with polymer vessels or with other technologies are eliminated. This is a valuable feature for trace analysis of challenging species such as dioxins. 3 4 GREATER RETURN ON INVESTMENT The competitive nature of the environmental analysis market requires today's laboratories to have innovative solutions that provide faster turnaround times. With throughput capabilities of 24 samples in only 40 minutes, the ETHOS X with fastEX-24 reduces overall analysis costs by increasing productivity. The combination of lower solvent volumes, less maintenance needs, and the use of inexpensive disposable glass vials decreases the cost per sample to enhance your lab's competitiveness and profitability.

The ETHOS X with fastEX-24 overcomes productivity WITH HIGHER SAMPLE AMOUNT limitations of other conventional approaches by enabling the extraction of a large number of samples in a single workday. Other technologies process one sample at a time sequentially, requiring long extraction cycles. The ETHOS X simultaneously processes 24 samples in only 40 minutes and eliminates cleaning steps by using disposable glass vials.
