Miniaturized Biospectral Logger Deployed at Mount Lassen

Miniaturized Biospectral Logger

On April 16-17, 2009, Nathan Bramall, Carol Stoker, and Jhony Zavaleta successfully tested the Miniaturized Biospectral Logger, a borehole fluorescence-detection instrument tuned to detect proteins. The instrument is only 5.1 cm in diameter and 1.4 m long but is sensitive to a single bacterium on a clay mineral background without the use of any consumables. […]

Gas Chromatography-Mass Spectrometry Resolution of Sugar Acid Enantiomers

A manuscript by George Cooper entitled: “Gas Chromatography-Mass Spectrometry Resolution of Sugar Acid Enantiomers on a Permethylated beta-Cyclodextrin Stationary Phase” has been accepted for publication in The Journal of Chromatograhy A. The manuscript describes the separation of laboratory standards of mirror-images (enantiomers) of individual sugar acids, e.g., glyceric, erythronic, ribonic, etc. This class of organic […]
