Rosemount Analytical

Rosemount Analytical

Based on years of reliable and repeatable BTU measurement using the Daniel Danalyzer GC platform, please see our current line of Gas and Liquid Chromatographs.


Process Gas Chromatographs are designed for applications within processing facilities and used in a variety of refining, petrochemical, power, and environmental applications where selected components in gaseous or liquid streams must be precisely monitored on a continuous basis.
Danalyzer natural gas chromatographs are engineered for applications where critical gas measurement is needed, including C6+ BTU/CV for custody transfer, C9+ analysis with hydrocarbon dew point calculations, trace contaminant monitoring (including C6+ with H2S) for pipeline integrity, product quality for LNG or NGL’s, and other customized applications for your natural gas analysis needs.

With over 3,000 CEMS installations in the field worldwide, Rosemount Analytical combines the expertise and field-proven technologies with the most rugged sample conditioning and extraction systems in the industry to provide superior measurement accuracy and repeatability. Designed in consideration of CEM regulations as specified in clean air laws around the world, including U.S EPA 40 CFR Part 75 and 40 CFR Part 60, we help you meet data reporting requirements, maintain emissions compliance, and ensures certification and compliance with your local and international regulatory agencies.

    The 1500XA Gas Chromatograph is an air-bath style GC engineered for complex applications requiring multiple detectors and parallel chromatography. The 1500XA is ideal for your natural gas processing applications where instrument air is available and requires higher oven temperatures than are available in a heat-sink design. As with other Danalyzer’s, the 1500XA is rated for 0 to 130 °F (-15 to 55 °C) operation, providing the most stable analysis for an air-bath oven and reducing your installation and utility costs significantly.

    BTU and 0-300 PPM H2S measurements are used for EPA Federal Regulation 40 CFR part 60, subpart Ja compliance where Continuous Emissions Monitoring Systems are required by the EPA.

  • A+ Genie Probe Regulator (GPR)

    The GPR™ consists of a housing and a membrane-tipped probe regulator. The housing is installed in a depressurized pipeline through a vertically mounted thread-o-let or flange, and contains a “foot valve” in its lower end. Inserting the probe into the housing opens the “foot valve”, allowing pipeline gas to flow[…]
