How EASY can microwave sample preparation become?

The range of sample types requesting microwave digester and analysis for trace metals has grown significantly in recent years. At the same time, sample workloads have increased, and turnaround time reduced.
In addition, the development of collision cell ICP-MS has widened its applicability to more complex sample types placing additional demands on microwave acid digestion: its lower detection limits and fast analysis time require lower blank contribution and higher throughput in sample preparation techniques.
In response to these demands, Milestone has developed the new microwave digestion oven ETHOS EASY, specifically designed for closed vessel microwave acid digestion, with full control of all reaction parameters.
  • Safety by design. Best microwave hardware, temperature and pressure sensors
  • Ease of use and control. easyTEMP temperature control and advanced rotor technology
  • Performance and throughput. EasyCONTROL operating software
  • Know-How and Support. 30-years experience at your lab with the Milestone Connect
  • Flexibility. Rotor-based digestion system for hundreds of applications.
Microwave digestion system ETHOS EASY covers the whole range of samples from routine to high-end applications including US EPA method 3052 for sediments, sludges and soils and US EPA method 3015 as microwave digester of aqueous samples and extracts.

THE LARGEST STAINLESS-STEEL MICROWAVE CAVITY

The microwave cavity has a volume of over 70 liters, the largest currently available. Therefore, digestion rotors with more sample places can be accommodated, incresing both productivity and sample throughput. Secondly, it improves the inherently safety because a larger cavity contains gases escaping from vessels in a more efficient way, in case of a sudden over pressurization.

PRESSURE-RESPONSIVE DOOR FOR MAX SAFETY

For additional safety, the ETHOS EASY features a full stainless steel door with an innovative opening and self-resealing mechanism. Should there be a sudden over pressurization of the cavity, the door slightly opens for rapid and safe pressure release and the microwave power is instantaneously cut off. Immediately afterwards, the door is pulled back, resealing the microwave cavity.

THE MOST POWERFUL MICROWAVE DIGESTER

The ETHOS EASY is equipped with two 950 Watt magnetrons for a total of 1900 Watt. The system additionally employs a rotating diffuser that evenly distributes the microwaves throughout the cavity. High power coupled with this diffuser enable very fast heating of high throughput rotors and the complete digestion of the most difficult samples.

LIVE MONITORING WITH MILESTONE SafeVIEW

The ETHOS EASY integrates the Milestone safeVIEW, a high definition digital camera interfaced with the instrument terminal. It allows the chemist to monitor the progress of the digestion whilst being fully protected by the instrument's all-stainless steel door. A video of the entire run is shown in real time.

SENSORS

for unparalleled digestion control

In a digestion process, the temperature controls the sample decomposition and directly affects digestion quality. Milestone pioneered the use of infrared sensors combined with an in-situ temperature sensor. Today, Milestone innovates again by combining all the benefits of in-situ and infrared sensors into the Milestone easyTEMP, a direct contactless temperature sensor.

Temperature control with easyTEMP

The easyTEMP contactless sensor directly controls the temperature of all samples and solutions, providing accurate temperature feedback to ensure complete digestion in all vessels with superior safety. This technology combines the fast and accurate reading of an in-situ temperature sensor with the flexibility of an infrared sensor.
In combination with our 'vent-and-reseal' vessel technology, easyTEMP direct contactless sensor ensures complete and safe digestions without any loss of volatile compounds.
  • Increased ease of use and productivity
  • Enhanced control in all vessels
  • Fast and accurate temperature measurements
  • Superior digestion quality
