Agilent 990 Micro GC - Natural Gas Analyzer B and the Extended Version

Agilent 990 Micro GC - Natural Gas Analyzer B and the
Extended Version
Natural Gas Analyzer B
The Agilent 990 Micro GC - Natural Gas Analyzer B is used to analyze methane, carbon dioxide,
hydrogen sulfide, and light hydrocarbons up to n-nonane in natural gas.
The Agilent 990 Micro GC - Natural Gas Analyzer B is a basic cabinet micro GC equipped with two
channels:
• PoraPLOT U channel with a backflush option
• 6 meter CP-Sil 5 CB channel
Natural Gas Analyzer B Extended
The Agilent990 Micro GC - Natural Gas Analyzer B Extended is used to analyze hydrogen, nitrogen,
oxygen, methane, carbon dioxide, carbon monoxide, hydrogen sulfide, and hydrocarbons up to
n-nonane.
The Agilent 990 Micro GC - Natural Gas Analyzer B Extended is a basic cabinet and a channel
extension cabinet micro GC equipped with three channels:
• PoraPLOT U channel with a backflush option
• 6 meter CP-Sil 5 CB channel
• CP-Molsieve 5A channel with a backflush option
The Natural Gas Analyzer B Extended version is equipped with a dual carrier gas option for the
CP-Molsieve 5A channel. It is made flexible for analysis of hydrogen and helium on the
CP-Molsieve 5A channel if required. For the analysis of helium on the CP-Molsieve 5A channel, the
carrier gas must be argon. All analyzers are factory tuned on helium as a carrier gas.
Before starting up the Agilent 990 Micro GC - Natural Gas Analyzer, ensure that correct carrier
gases are connected for all channels. For all types of analyzers, the required carrier gas is helium.
However, to analyze helium on the CP-Molsieve 5A, the carrier gas must be argon. The required
pressure for carrier gas is 550 kPa ±10 kPa (80 psi ±1.5 psi).
