The μPGC 990 from SRA Instruments is a micro process gas chromatograph NMi certified according to OIML R140:2007 Class A, ready for the analysis of blends up to 20% hydrogen blended with natural gas or biomethane.
Main features:
-
NMi certification for hydrogen blending. Parts Certificate TC13107 (October 2025) for blends up to 20% hydrogen in natural gas/biomethane. Ready for future Italian and European directives on hydrogen blending.
- Rapid Analysis: 90 Second Full Composition. Complete analytical cycle in just 90 seconds for all certified components (C1-C6+, N2, O2, CO2, H2). Real-time gas quality monitoring with rapid response for process and safety control.
- Helium as the unique Carrier Gas. Unlike architectures that require helium + argon, the μPGC 990 uses only helium (99.9995%). It simplifies logistics, reduces operating costs, and eliminates interference. Maximum repeatability for custody transfer measurements.
- Modular architecture with Maintainable Modules. Selective maintenance of individual independent analytical channels, without extended system downtime. Replaceable modules reduce MTTR to < 2 hours. Robust design for MTBF, > 8760 hours in continuous applications.
- Programmable Automatic Calibration. Automatic calibration at variable intervals (max. 1 week) with certified, traceable gases. Accountable alarms for response factor deviations, temperatures, and out-of-limit pressures. Compliant with NMi procedures.
- Full integration with DCS/SCADA. Modbus RS232/RS485 communication, Ethernet TCP/IP. Web interface for remote control. Alarms accountable on Modbus registers. Legally relevant data protected with password and hardware jumper.
