MAXUM edition II

Description

This process gas chromatograph, which has resulted from decades of international experience and technology development, leads the industry in capability, flexibility and reliability.

The Maxum edition II is used in all branches of the fine chemicals, refining and hydrocarbon processing industries. It performs chemical composition analysis of gases and liquids that are present in all phases of production. The Maxum is built for installation in harsh environments either directly online or nearby in at-line process measurement laboratories. Its application flexibility allows it to analyze samples of feedstock, partially processed streams, final products and process by-products including wastes and environmental hazards.

An addition to the MAXUM GC analysis platform is a modular oven option. The modular oven option is an airless oven design where complete chromatograph modules are snapped into place. Removal and replacement of a module can be performed in mere minutes, dramatically lowering operation and maintenance of the gas chromatograph. The module can then be repaired at the user’s convenience in their maintenance shop or returned for refurbishment at Siemens.

MAXUM edition II with its combination of different analytical components offers a wide range of analytical possibilities. It is therefore possible to solve highly different measuring tasks with just one product. This reduces the costs for investment, training and stocking of spare parts.
