Introducing the MAX300-CAT
Fast, Flexible Quantitative Gas Analyzer

The MAX300-CAT is a high-sensitivity, quantitative gas analyzer for catalysis, reaction monitoring, and environmental research.

Fast and powerful, this quadrupole mass spectrometer performs high precision quantitative analysis on every component in a gas or vapor mixture, and can be equipped for the fully-automated sampling of multiple gas channels.

With the ability to track concentration changes from ppb levels to 100% and continuous data updates in seconds, the MAX300-CAT provides a compact, flexible platform optimized for gas reaction studies in catalysis, bioreactor control, process development, and environmental analysis.


MAX300-CAT Laboratory Gas AnalyzerThe MAX300-CAT is fast, compact, and easy to use.It can measure any gas or vapor sample concentrationfrom ppb levels to 100%.

Laboratory Gas Analyzer Features

• Measures any gas or vapor sample
• Real-time analysis of the input and
effluent streams reveals what is happening
in the reaction
• Fast response: measures changes to
sample concentration in <300 ms
• High sensitivity: detection limit 50 ppb
• Data acquisition: up to 1000
• 1-100, or 1-300 amu mass range
• Complete quantitative sample composition
• Sample selector options for up
to 61 sample streams

MAX300-CAT Quadrupole Advantage

The mass spectrometer uses an ionizer to break sample molecules into charged fragment ions that are separated based on their mass-to-charge ratio as they move through the electric fields generated by the quadrupole mass filter. The ions register a current at the detector, creating a set of peaks called a mass spectrum. Each compound has a unique spectrum, making mass spectrometry a highly selective, flexible technique.


Accurate Data, Endless Utility

Simply select the gases to measure, or the mass range to scan, in the software and the MAX300-CAT is configured to monitor a new reaction or process.
