Online Gas Analysis for Weatherproof or Hazardous Area Locations - ProMaxion

THE NEED

Many batch and continuous process control applications require the measurement of one or more process chemicals. These measurements are often needed at very fast update speeds often from multiple sample points. Many optical techniques cannot meet these requirements, especially when multiple sample points are required. Likewise, the response speeds of chromatographs are often too slow to be used on multiple sample points. In addition, chromatographs are most often limited to a single application or process type. A process analyzer is needed for applications that require a fast, accurate process analyzer which can monitor varying chemicals from multiple sample points.

THE SOLUTION

AMETEK's ProMaxion process mass spectrometer offers real-time analysis in a reliable easy-to-use package for a wide range of industrial applications. Real-time process monitoring of up to 32 components is straightforward with ProMaxion's powerful, easy-to-use Process 2000 software. Complex overlapping spectra are handled automatically and data output directly in concentration units. Different calibration and analysis methods can be assigned to each sample port.

Mass spectrometry is a very rapid analytical method allowing analysis of multiple sample streams in seconds and can directly replace gas chromatographs and other discrete analytical devices. This field-proven system, combined with AMETEK's more than 30 years' experience in the process analyzer business, means you can depend on ProMaxion for your critical process analysis and control applications.

The ProMaxion can be custom-designed to monitor just about any type of gas stream, depending on sample pressures, hazardous area requirements, particulate levels and number of sample points. Automated sample switching allows unattended analysis of process and calibration gases. The multiport gas sample inlet system consists of multiple valves and a capillary restriction in an enclosure heated to prevent condensation. A membrane inlet system is incorporated for gas sampling applications.
