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.
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.
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.
Hundreds of applications, including all US EPA methods, are preloaded in the ETHOS EASY terminal, virtually eliminating any need for method development. To further simplify the workflow in the lab the ETHOS EASY is equipped with a backlit logo that indicates the actual status of the digestion process.
