Model 292B Portable Natural Gas Chromatograph

The AMETEK Model 292B natural gas chromatograph is designed as a truly ‘portable’ analyzer.


The AMETEK Model 292B natural gas chromatograph is designed as a truly ‘portable’ analyzer. An integrated sample inlet manifold allows for single connections of sample and drive (carrier) gases, allowing for flexible installation either as a stand-alone analyzer, or integrated onto a mobile platform such as a truck or other vehicle. On-site analysis not only eliminates the concerns over accurate sample acquisition and transport, it also eliminates the DOT concerns over transporting natural gas samples.

Analysis begins at a single touch of a button. Sample transport, signal integration and system diagnostics are handled within the unit to ensure accurate, reliable and repeatable analysis.
