	A large column installation space This oven accommodates a maximum of four 50-cm columns, which are usually used for measuring sugar contents and GPC analyses. A manual injector can be installed within the module. Wide temperature control range The cooling function provided as standard equipment permits a wide temperature control from 5 to 85(at aroom temperature of 20). Preheating system The preheating system is adopted in the same way as the Model L-2300. Preheating section customizable by user In analyses at a high flow rate, the retention time varies depending on the ambient temperature unless the preheating function is provided. This is because the temperature at the top of the column decreases due to an eluent to cause a temperature gradient on the inside of the column. The preheating section of the Model L-2300 column oven can be adjusted to an optimum length according to the flow rate, allowing you to carry out analyses without being affected by the ambient temperature. Furthermore, since the autosampler can be directly connected to the column without using a coupling, there occurs no dead volume that would otherwise cause a decrease in resolution. A wide range of applications Two sets of the three types of valves (option) can be controlled simultaneously. The time program is available for switching the temperature and optional valves at any desired time. This column oven can also be used for sample condensation, multidimensional LC, and other applications.
