Novel ionization reagent for the measurement of gas-phase ammonia and amines using a stand-alone atmospheric pressure gas chromatography (APGC) source. [PDF]
, 2020 RationaleContaminants present in ambient air or in sampling lines can interfere with the target analysis through overlapping peaks or causing a high background. This study presents a positive outcome from the unexpected presence of N-methyl-2-pyrrolidone,

A study on the fragmentation of sulfuric acid and dimethylamine clusters inside an atmospheric pressure interface time-of-flight mass spectrometer [PDF]
Atmospheric Measurement Techniques, 2022 Sulfuric acid and dimethylamine vapours in the atmosphere can form molecular clusters, which participate in new particle formation events. In this work, we have produced, measured, and identified clusters of sulfuric acid and dimethylamine using an ...

Alkaline Diuresis as Treatment for 2,4-D Dimethylamine Herbicide Intoxication
European Journal of Case Reports in Internal Medicine, 2022 Acute intoxication with 2,4-D dimethylamine is rare, often fatal and can cause signs and symptoms in different organ systems. This case report describes the effectiveness of alkaline diuresis as a life-saving treatment for chlorophenoxy intoxication ...

From quantum chemical formation free energies to evaporation rates [PDF]
Atmospheric Chemistry and Physics, 2012 Atmospheric new particle formation is an important source of atmospheric aerosols. Large efforts have been made during the past few years to identify which molecules are behind this phenomenon, but the actual birth mechanism of the particles is not yet ...

The charging of neutral dimethylamine and dimethylamine–sulfuric acid clusters using protonated acetone [PDF]
Atmospheric Measurement Techniques, 2015 Sulfuric acid is generally considered one of the most important substances taking part in atmospheric particle formation. However, in typical atmospheric conditions in the lower troposphere, sulfuric acid and water alone are unable to form particles.
