The MAXUM Edition II offers unique variety

The MAXUM Edition II is used to measure the chemical composition in gases and evaporable liquids in all stages of production and in all areas of refineries, oil refining, and chemical industries. It was developed specifically for installation in harsh processing environments, to operate either directly online at the process or nearby.

 

The application flexibility of the MAXUM Edition II allows for the analysis of feedstock, by-products and end products, for quality measurement, and for the determination of waste products. Its versatile features offer the best possible analytical results at low operating costs thanks to a wide selection of components such as injectors, ovens, detectors, and separation columns, as well as components for column switching. Liquid samples can be optimally dosed by the use of a liquid injection valve. Highly sensitive detectors ensure a reliable trace analysis through precise sensors. An additional benefit is the economic efficiency resulting from the single and double-oven concept plus the modular oven. In addition, networked devices can be monitored in real time by the workstation.

Adaptable to any analysis task

The MAXUM ed. II with modular oven is an option of the MAXUM GC analytic platform and is comprised of an electrically heated oven with complete insertable chromatography modules. Removal and replacement of a module can be performed in mere minutes, dramatically reducing operating and maintenance times regarding the gas chromatograph. The module can be repaired at the user’s convenience in their maintenance shop or returned to Siemens for refurbishment. With its combination of different components in a modular type system, the MAXUM ed. II offers a variety of analytical options. It is therefore possible to perform different measurement tasks with just one product, reducing costs for investment, training, and spare parts for our customers.

The perfect match of high performance and minimal maintenance requirements

The MAXUM ed. II is the leading gas chromatograph in the process industry. It is used worldwide and has proven itself by its high degree of precision and reliability in the analysis of gases. We have now combined these excellent features with a simplified handling, culminating in the MAXUM ed. II type modular oven.

Special analytical tasks require stable temperatures in the oven to optimize separating performance of the components. The requirements for optimum separation performance are met with our two oven types. The airless oven provides extremely stable isothermal temperatures with high control accuracy, completely without the use of air. The airbath oven offers both isothermal and temperature-programmed operation with air supply.
