Advanced User Interface

The ETHOS 1 is operated via a compact terminal with bright, full-color, touchscreen display. The terminal runs the Milestone’s unique EasyCONTROL software, to provide simple, userfriendly control of the microwave sample preparation process.

EasyCONTROL software

Milestone’s new EasyCONTROL software is the most advanced and powerful operating system in the field of microwave sample preparation.
Automatic, real-time monitoring and feedback-based control of multiple parameters offer unsurpassed process control.Simply recall a factory stored program or create a new one. Press ‘Start’, and the system will automatically follow the drawn temperature or pressure profile, utilizing a sophisticated PID algorithm. The most important advantages are:

On-line control of all parameters.
Direct temperature control 20 times per second.
Temperature driven microwave power output.
Reaction is controlled at any temperature, not only once a set temperature is reached.
Better control of exothermic reactions.
Same digestion quality for different sample sizes.
One method only needed for any number of samples.

Better control of exothermal reactions

Digestion of 1,2 grams of rice with 10 ml HNO3. Notice that at 120°C, when the sample decomposition takes place, the power is automatically reduced to zero to prevent temperature overshooting. This is a unique advantage of the Milestone EasyCONTROL software

Same digestion quality for one or multiple samples

0,25 grams of feed with 10 ml HNO3. The average microwave power during the temperature ramping step is 120 watts, when 1 vessel is used.

0,25 grams of feed with 10 ml HNO3. The average microwave power during the temperature ramping step is 400 watts, when 6 vessels are used. The temperature profile remains unchanged.

Easy data transfer by EasyDOC Windows-based software

The ETHOS 1 terminal offers the ability to save methods and runs on a Windows-formatted flash card. The flashcard can be directly read by any laptop with a PCMCIA port or, via an adapter, through a USB port. All methods and runs are saved, and can be transferred to/from the hard drive of the computer. Therefore there is virtually unlimited memory for storing all your sample preparation data. Furthermore, with Milestone’s Windows™-based EasyDOC software, it is possible to convert the data coming from the ETHOS 1 terminal into a standard format readable by any database or spreadsheet software (Excel™, etc.).
