Short summary
Formaldehyde is an important atmospheric species that is present at all times throughout the troposphere. Accurately measuring formaldehyde is necessary for understanding key atmospheric chemical cycles. We describe here the first wide-scale demonstration of the gas chromatographic mass spectrometric (GC/MS) technique (NSF NCAR TOGA-TOF (National Science Foundation - National Center for Atmospheric Research - Trace Organic Gas Analyzer with Time-of-Flight mass spectrometer)) for quantifying formaldehyde in the atmosphere and we show this technique to be highly sensitive and selective.
