Page 3: The Agilent Biogas Analyzers
The Agilent 490 Micro GC Biogas Analyzer is a factory tuned analyzer specific for biogas analysis. Two types of Biogas Analyzers are available: Agilent 490 Micro GC Biogas Analyzer and the Agilent 490 Micro GC Biogas Analyzer Extended. -
Page 4: Checkout Information
The Biogas Analyzer is factory tuned including appropriate settings for backflush times for the CP- Molsieve 5A and CP-PoraPLOT U channel. Final checkout of the Agilent 490 Micro GC Biogas Analyzers is performed with a Universal Gas Calibration standard. This contains helium, neon, hydrogen,... -
Page 5: Cp-Molsieve Channel
The Agilent Biogas Analyzers CP-Molsieve channel The CP-Molsieve 5A channel of the Biogas Analyzer analyzes permanent gases such as helium, neon, hydrogen, oxygen, nitrogen, methane and carbon monoxide. Figure 1 is a chromatogram of the Universal gas Calibration Standard analyzed on the CP-Molsieve 5A channel.

Page 6: Cp-Poraplot U Channel
The Agilent Biogas Analyzers CP-PoraPLOT U channel The CP-PoraPLOT U channel of the Biogas Analyzer is used to analyze carbon dioxide, ethane, hydrogen sulfide and n-propane. This channel and the sample inlet are Ultimetal deactivated which results in improved performance for hydrogen sulfide analysis. - Page 7 The Agilent Biogas Analyzers CP Sil 5 CB channel The CP-Sil 5 CB channel of the Biogas Analyzer Extended is used to analyze the hydrocarbon up to n-heptane. Hydrocarbons that are specified for this analyzer are i-butane, n-butane, neo-pentane, n-pentane, iso-pentane, n-hexane, and n-heptane. The Universal Gas Calibration Standard does not contain all these hydrocarbons.

Page 8: Tuning The Backflush Time
The Agilent Biogas Analyzers Tuning the backflush time For the CP-Molsieve 5A and the CP-PoraPLOT U channel, the backflush times must be tuned. For tuning, the Universal Gas Calibration Standard is recommended. The purpose of tuning the CP-Molsieve 5A is to get all methane on the column while all components such as moisture, carbon dioxide, ethane and higher hydrocarbons are backflushed. -
