Isothermal Oven - Siemens Maxum II Reference Manual

Electronics Enclosure
The Electronics Enclosure houses all the electronics and pneumatic modules required for
performing all temperature, valve control and analysis functions. The Electronics Enclosure
modules are interconnected using simple cable connections made to each module. All modules
can be easily removed and replaced. The Maxum II software recognizes each Maxum II's
application, hardware components and network configurations.

Isothermal Oven

The Maxum ll has a wide variety of isothermal oven configurations. Both air bath and airless
ovens are available. All air bath configurations are available with Vortex cooling for sub-
ambient temperature operation. A program temperature oven option is available for Maxum II
applications where isothermal, multi-dimensional chromatography is not practical. Typically
the program temperature Maxum II is used for Motor Gasoline (ASTM 3710) & Simulated
Distillation (ASTM 2887) applications.
