3000 Micro GC Operating Manual
11.5.1 RGA Checkout Gas
Refinery Gas Analyzer (RGA) Checkout Gas may be used during installation of a
3000 Micro GC configured for refinery gas composition analysis to verify chemical
performance.
lists the component concentrations.
NOTE: Do not use RGA Checkout Gas as a calibration standard for specific
refinery gas applications. Since refinery gas composition varies greatly
among various petrochemical processes, acquire a calibration standard
that meets specific requirements.
