Other Descriptions for Sampling and Analyses In the AGAGE global network program, continuous high frequency gas chromatographic measurements of six anthropogenic gases are carried out at globally distributed sites.
AGAGE uses a new fully automated system from the Scripps Institution of Oceanography containing a custom-designed sample module and HP5890 and Carle Instruments gas chromatographic components.
Individual measurements are generally made more than 30 times daily at each site for AGAGE.
