Diablo 5000A Real-Time Gas Analyzer
The Diablo 5000A 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 5000A 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.
Diablo 5000A RTGA Performance Benefits
- Fast, real-time response to process changes
- Flexible, rugged, fast-responding direct process sampling interface
- Uses a high-performance Agilent Technologies 5975 or 5977 quadrupole mass spectrometer (5975C or 5977A MSD)
- Quick and easy conversion of 5975/5977 MSD from the direct RTGA-MS configuration to standard GC-MS configuration
- Linear response and stable, reliable quantitative analysis with active compensation for changes in process pressure
- Hardware and software enhancements enable detection of low-mass species like hydrogen with the 5975/5977 MSD
Sampling Interfase
The 5000A RTGA Process Sampling Interface
- Differentially-pumped, dual-orifice design is simple, flexible, robust, and reliable
- Very fast response compared to simple capillary interfaces
- Inert – semiconductor-grade, electro-polished stainless steel
- High-performance capacitance manometer can be used to monitor and actively compensate for sample-pressure variations
- Custom-fitted interface heater blanket and controller
- Orifice size is used to control amount of sample entering the MS
- Can be adjusted to accommodate vacuum to high-pressure sample pressures, and trace to %-level analytes.
- Orifice disks can be changed easily without venting the MS
Reliable Calibration and Quantitation
One of the important features of the 5000A RTGA is its ability to perform stable and reliable quantitative analysis. From the extremely stable 5975 or 5977 MSD, to the process sampling interface and the MS Sensor software, the RTGA has been designed with quantitative analysis in mind.
The following calibration plots illustrate the linearity of the RTGA in both trace and high-level applications:
MS Sensor Process Analysis Software
The MS Sensor software is designed to allow simple, yet flexible acquisition and display of real-time process data using the Agilent Technologies 5975/5977 MSD and other kinds of instruments like pressure sensors and flow meters.
