MicroSAM , the newest on-line Process Gas Chromatograph from Siemens, brings a new dimension to the industry - small! Using modern silicon micro-machining techniques achieves miniature size while simultaneously increasing power and versatility.

The analysis module integrated in an explosion-proof housing no bigger than a  small platter contains everything required to separate and detect the measured components.

Every MicroSAM measures a maximum of three sample streams plus one calibration stream. It is possible to install multiple MicroSAM analyzers at different measuring points in a plant, integrated in a complete analyzer network. MicroSAM analyzers together with MAXUM Edition II can be easily connected to a process control system and permit several process streams to be analyzed simultaneously. Such systems are easy to implement and achieve more information.

  • Option of mounting in the field; user friendly and cost-effective installation, minimal infrastructure requirements, faster analysis

  • Compact and modular construction means less space taken up in the analysis block, simple and cost-saving maintenance and repair

  • Precise measurement results - the thermal conductivity detectors monitor the entire separation path from the injection through to all columns or purge outlets

  • Simple remote control with Windows-based software and Ethernet communication
