AccuChrome™ GC

Btu & Hydrocarbon Analyzer

AccuChrome™ GC for Btu & C9+ Hydrocarbon

Btu + Hydrocarbon content for Natural Gas Processing and Custody Transfer.

AccuChrome is designed for critical monitoring in the harshest environments.

Whether you’re performing Btu and constituent analysis of natural gas for custody transfer, process optimization during natural gas fractionation, or 40 CFR 60 Subpart JA flare-gas emissions monitoring for regulatory compliance – you need precise, real-time measurements you can count on.

With auto calibration and validation capabilities to enable fully hands-off operation and the utmost in ease-of-operation, consistent, field-proven performance – and value, Galvanic’s AccuChrome analyzer can help you optimize your processes for better quality and lower costs. On rare occasions when there is a problem, it’s easy to address right then and there – the design enables ready access to all components, each of which are fully field-serviceable – reducing downtime and the need for costly module replacement.

    Rugged Thermistor-Based Detector

    Less susceptible to fouling than micro-machined technology, the AccuChrome GC’s thermal-conductivity detector is able to withstand corrosive compounds such as H2S. Plus, Galvanic’s detector will not burn out on loss of carrier gas!

    Airless Heat-Sink Oven

    An airless heat sink oven maintains a constant temperature of columns, valves, and thermal-conductivity detector for reliable and accurate results. No external air source required!

    Auto Calibration & Validation

    Calibration and validation is simple on the AccuChrome GC system. Auto validation lets you analyze the calibration standard without adjusting response factors or retention times. The AccuChrome GC supports two calibration standards for enhanced measurement of streams with widely varying hydrocarbon concentrations.

    Intuitive Operator Interface

    The AccuChrome GC Windows® software provides a powerful tool for operation, diagnostics and data handling. View and save chromatograms and analysis results, review or modify analysis settings, set up networking, generate reports, and control several other

    Easy Analyzer Networking & Data Communications

    Remote login and troubleshooting is easy via the AccuChrome GC Ethernet connection. The AccuChrome GC will support Ethernet Modbus TCP/IP and up to eight additional serial ports. Select a standard industry-compliant modbus list, generate customized modbus lists, or create and access multiple modbus lists via Scada. You can operate the TCP port as either master or slave; the AccuChrome GC supports up to 16 masters simultaneously.
