prominence column ovens - CTO-20A and CTO-20AC can accommodate multiple columns, mixing chamber, two column switching valves as well as two manual injectors. The fan allows equal temperature distribution inside the whole compartment. The temperature control range for the CTO-10A extends from RT + 10°C to 85° C and for the CTO-20AC the temperature control range extends from RT -10°C to 85°C. Additionally Prominence column ovens have the capability for temperature gradient programming. A built-in ready state sensor with flexible ready range and wait time settings assures that samples are only injected after the temperature has been completely stabilised.

For tracing the column history a Column Management Device (CMD) can be used and connected directly to the column oven. The high pressure switching valves, FCV-12AH and FCV-14AH, can be directly controlled by the column oven. The actual valve positions of the high pressure switching valves are displayed on the column oven display. Constant analytical conditions can be achieved due to the possibility of accommodating all required modules and accessory, e.g. an FCV-12AH 6-port valve for automatic sample pre-treatment with trap column.

An environment temperature sensor allows for exact and precise temperature control of all column ovens. The column ovens can as well be used in stand alone mode and controlled via the build in keyboard.
