CTO-20A/20AC Column Oven
Prominence HPLC Column Ovens
Large-capacity, forced hot-air circulation units, the CTO-20A/20AC HPLC column ovens precisely regulate the temperature around the column. Automatic fan-speed control varies with the set temperature to provide stable analysis that is not influenced by the ambient temperature.
CTO-20A - Precise Temperature Control
A forced-air circulation-type column oven, the CTO-20A can regulate the temperature from 10ºC above room temperature to 85ºC. Rapid temperature equilibration allows complex temperature programs incorporating linear and/or step-wise increases and decreases in temperature.
CTO-20AC - Column Cooling Supported
The CTO-20AC can heat and cool the column compartment, utilizing a Peltier cooling device to provide sub-ambient conditions. Temperature control is regulated over a wide range, from 10ºC below room temperature to 85ºC, for increased reproducibility and separation performance.
Precise Temperature Regulation
The interior of the oven is precisely regulated with a high-performance thermistor. The temperature is calibrated at two different temperatures to ensure a high level of temperature accuracy.
Large Inner Space
In addition to the column, other system parts can be accommodated. These include:
- Manual injector
- Gradient mixer
- High-pressure flow-line selection valves (2-position/6-port valves or 6-position/7-port valves, two in total)
- Conductivity-detection cell block
- Pre-or post-column reaction coil
Column Management Device (CMD)
Both the CTO-20A and 20-AC support the CMD. The CMD provides:
- Recorded information about column usage
- Amount of mobile phase delivered
- Composition of the last mobile phase used
- Number of samples injected
This information is managed through an LC workstation (with LabSolution) or a PC in the network using the CBM-20A System Controller's Web-control function.
Optional Flow-Line and Column Selection Valves
The FCV-20AH2/20AH6 valves are stand-alone, high-pressure, flow-line or column selection valves. The valve position is controlled by event signal input. Direct control is also possible from the unit itself.
