Using Short-Range Modems for Data Transfer with the LI-7000 CO₂/H₂O Analyzer

Friday, September 5th, 2008

Some users of the LI-7000 CO₂/H₂O Analyzer use modems to transfer data over large distances (e.g. the Short Range Modem SRM-3A, which can transfer signals up to a distance of approximately 2.5 miles). When using modems of this type with the LI-7000, data does not travel through the modem to the computer. This is due…

Making One-Sided Leaf Measurements with the LI-6400/6400XT

Friday, September 5th, 2008

LI-COR occasionally receives inquiries from users of the LI-6400/6400XT Portable Photosynthesis Systems who want to measure gas exchange on only one side of their leaf, due to differences in leaf morphology (e.g. different stomatal ratios on either side of the leaf). This can be done fairly easily with the LI-6400 sensor head, by simply masking…

LI-8100 Long-Term Chambers Suggested End-of-Season Maintenance

Friday, September 5th, 2008

Before beginning a new field season, some routine LI-8100 chamber maintenance should be performed by the user. A few simple procedures can be used to inspect and clean the chamber, and replace any damaged components. Most materials needed for replacement are included in the Spare Parts Kit that was shipped with the chamber. Spare parts…

Conference papers for Ag and Forest Meteorology Conference and Atmospheric BioGeoSciences

Friday, September 5th, 2008

LI-COR conference papers for Ag and Forest Meteorology Conference and Atmospheric BioGeoSciences are now available on-line. Influence of instrument surface heat exchange on CO₂ flux from open-path gas analyzers by George G. Burba, Dayle K. McDermitt, and Dan J. Anderson (http://ams.confex.com/ams/pdfpapers/137086.pdf) From the introduction: “There have been many comparisons between open-path and closed-path sensors demonstrating…

LI-7000 Used To Regulate Suspended Animation

Friday, September 5th, 2008

At the Fred Hutchinson Cancer Research Center in Seattle Washington, researchers in the Institute’s Basic Sciences Division are making interesting use of the LI-COR LI-7000 CO₂/H₂O Gas Analyzer. A team of scientists from the laboratory of Dr. Mark Roth uses the LI-7000 to measure CO₂ exhalation as a proxy for metabolism in a variety of…
