The Maxum edition II system, hereafter referred to as Maxum II, represents a significant advance in process chromatography. This was accomplished by combining the best of the Siemens Advance Maxum and PGC 302 gas chromatographs into a single platform analyzer. From oven and electronic components to software and communication networks, the system is modular. Pre-configured application modules are available for many common measurements. A Maxum II system offers a wide range of detector modules including Thermal Conductivity, Flame Ionization, Flame Photometric, and the Pulsed Discharge Detector (which can operate in Helium Ionization, Photoionization, and Electron Capture modes). All detector modules are available for both air bath and airless ovens. The Maxum II oven is designed so it can be divided into two independently heated isothermal ovens for parallel chromatography applications. A single air bath oven can accommodate up to 3 detector modules, and an airless oven can house a single detector module in each oven. The Maxum II Maintenance Panel provides maintenance personnel with access to all maintenance functions and data. In addition, the Maintenance Panel will display both real time and archived chromatograms. A PC based network workstation incorporates Gas Chromatograph Portal software.
