TEMP-SURE: accurate and precise temperature control in ALL vessels

The ETHOS 1 is equipped with the most advanced reaction sensors, including contact-less temperature and pressure control in all vessels, and direct temperature and pressure control in a single reference vessel.
For the first time TEMP-SURE allows monitoring and controlling of both external and internal temperature of all vessels in real time during the digestion. This unique stateo f-the-art system includes the ATC direct temperature control in a reference vessel and the IRT contact-less infrared temperature control for all vessels. Both sensors are interfaced with a microprocessor-controlled rotor positioning system.
This latter device enables the software to identify which vessel is passing in front of the infrared sensor while the rotor is turning. The software correlates the internal and external temperatures data and all profiles are displayed with the corresponding ID code of the vessel. With TEMP-SURE the chemist receives confirmation that each vessel has reached the set target temperature and that this temperature has been held for the appropriate time to allow completion of the sample preparation process.
The US EPA method 3052, suitable for digestion of environmental samples, such as soils and sediments, is a typical example, specifying a temperature of 180° C +/- 5° C to be held for 10 minutes.
This new development allows full documentation of the digestion temperature of all samples and not only a single reference one. A clear benefit for the Quality Assurance of the sample preparation process.

Direct temperature control

The ATC Automatic Temperature Control system allows for direct continuous monitoring and control of a reference vessel up to 300°C. The temperature sensor is housed in a thermowell and protected from chemical attack by a multiple layer of PTFE and inert material, ensuring trouble-free operation.
