The Diablo 5000B Real-Time Gas Analyzer (RTGA) is a real-time chemical measurement tool for continuous process improvement. It is ideal for applications where fast chemical analysis is required, such as monitoring process transients and dynamic continuous reactions. The 5000B RTGA can be used for fuel cell gas analysis, syngas monitoring, catalyst research, monitoring of volatile solvent residues, pharmaceutical reactor headspace monitoring, and many other applications.
Overview
Fast Real-Time Gas Analysis by Direct Mass Spectrometry

The Diablo 5000B Real-Time Gas Analyzer (RTGA) provides a real-time chemical measurement tool for continuous process improvements. It is ideal for applications where very fast analysis is required, such as monitoring for transients and continuous reactions. The Diablo RTGA can be used for fuel cell gas analysis, syngas monitoring and many other applications.
Diablo 5000B RTGA Performance Benefits
- Fast, real-time response to process changes
- Flexible, rugged, fast responding direct process sampling interface. Multiple interface configurations are available for high-flow, high-pressure, low-flow, fast-response, and vacuum sampling.
- Uses a high-performance Agilent Technologies 5977 quadrupole mass spectrometer (5977 MSD)
- Easy conversion of the 5977 MSD from direct RTGA/MS to standard GC/MS configuration
- Linear response and stable, reliable quantitative analysis with active pressure compensation
- Easy to use MS Sensor 4.0 process analysis software and Application Builder software for easy creation of methods
- Hardware and software enhancements allow for hydrogen and helium detection
Diablo 5000B RTGA News and Announcements
A recent Windows 10 update introduced an incompatibility with the MS Sensor 3.0 software that caused certain controls to display and function incorrectly and also caused the program to crash when starting an acquisition. We were able to identify and update the incompatible software library (an older version of the Microsoft Common Controls library) and […]

Announcing the release of the Diablo 5000B RTGA and MS Sensor 4.0 software
Februrary 2019:
Antioch, CA – Diablo Analytical, Inc. is announcing the release of their new 5000B Real-Time Gas Analyzer (RTGA) for rapid, high-quality experimental measurement in the Engineering and Chemistry world. Along with the 5000B RTGA, Diablo Analytical is also announcing the release of the MS Sensor 4.0 Process Analysis Software.
The new modern, software and hardware capability allows more sample interface options to connect with a wide range of gas streams from experiments and provides for more simplified operation.
The Diablo 5000B RTGA Gas Analyzer is based on the industry standard, Agilent Technologies 5977B single-quadrupole mass spectrometer, a proven platform with worldwide local service.
The Diablo 5000B RTGA Gas Analyzer includes the new easy to use MS Sensor Application Builder software for rapid and quick evaluation of new gas streams for optimum instrument method conditions. Then, the software auto-generates the actual method for acquisition of data.
The Diablo 5000B RTGA Gas Analyzer includes the MS Sensor 4.0 software with new simplified calibration and pressure compensation functionality. The design of the hardware sample interface enables robust linear calibrations across different matrix gases and different sample pressures.
The History of the Real-Time Gas Analyzer
The hardware sampling interface technology and MS Sensor software were originally developed by Diablo Analytical and licensed to Agilent Technologies in 2001 to enable the Agilent 5973N MSD to be used for direct gas sampling and continuous process analysis. Agilent named that instrument the Agilent 5000A Real-Time Gas Analyzer (RTGA).
In February of 2007, Agilent and Diablo signed an agreement that enabled Diablo to take over development, manufacturing, sales and support of the 5000A RTGA.
In Februrary of 2019, Diablo released the 5000B RTGA and MS Sensor 4.0 software.
