Portable Gas Chromatograph Launched

AMETEK Process Instruments (USA), a specialist in online analytical instrumentation with one of the industry’s most extensive product line, has introduced the Chandler Engineering Model 292B portable gas chromatograph for the determination of the energy content (BTU) of natural gas.

The AMETEK Model 292B natural gas chromatograph is designed as a truly portable analyser. The Model 292B BTU analyser features a fully integrated sample handling system, rugged gas chromatograph (GC) module, and enhanced data processing and handling capabilities, including a state-of-the-art LCD colour display and user interface.

Gas analysis starts with the touch of a button. Sample transport, signal integration and system diagnostics are handled within the unit to ensure accurate, reliable and repeatable analysis. The unit’s advanced electronics platform accurately determines energy content, relative density and compressibility based on industry-standard calculation methods.

Integrated optimisation functions result in exceptional sensitivity and peak performance. An integrated sample inlet manifold allows for single point connections of sample and drive (carrier) gases, permitting installation either as a stand-alone analyser or integrated into a mobile platform such as truck, van or other vehicle.

Sample results, including “live” chromatograms, raw data information, analysis reports and calibration data can be easily viewed on the front-panel LCD display. System and analysis reports can be retrieved via a USB port, customised to meet user requirements, and printed directly from the unit using an industry standard USB printer port connection.

The Model 292B’s advanced software and two onboard computers allow the unit to calculate heating value, relative density and compressibility using the AGA-8 method. The system also analyses composition with exceptional accuracy. Oven temperature is precisely controlled, eliminating errors caused by ambient temperature fluctuations.

In addition, the unit’s Thermal Conductivity Detectors (TCD) provide extremely high sensitivity, even for low concentrations of components. The instrument’s TCD bridge is balanced automatically before each analysis to ensure peak performance and repeatability.
AMETEK has manufactured laboratory and gas chromatographs for more than 30 years. Its proprietary manufacturing process ensures that the Model 292B will maintain superior repeatability over its entire service life. Its experience in GC valve design further assures reliable and trouble-free operation.
