New techniques for the field detection of inorganic improvised explosive devices (IEDs) are urgently developed. Although ion mobility spectrometry (IMS) has been proved to be the most effective method for screening organic explosives, it still faces a major challenge to detect inorganic explosives owing to their low volatilities. Herein, we proposed a strategy for detecting trace inorganic expl...

A novel hydride generation atomic absorption spectrometric method is developed for speciation analysis of inorganic arsenic in flours. This method is based on the leaching of arsenic from sample slurry through the sonication followed by hydride generation in the slurry and determination of the corresponding hydrides. The content of arsenic (III) [As(III)] was determined under 1% HCl acidity con...

In previous communications by the authors (1935) data were presented on the effect of some electrolytes, and of ethanol, upon the evolution of carbon dioxide from glucose by yeast aymin. The electrolytes, in appropriate concentrations, stimulate the rate of evolution of the gas. The zymin is very sensitive to ethanol. The addition of phosphate does not decrease the sensitivity toward ethanol, w...

In atmospheric aerosols, water and volatile inorganic and organic species are distributed between the gas and aerosol phases in accordance with thermodynamic equilibrium. Within an atmospheric particle, liquid and solid phases can exist at equilibrium. Models exist for computation of phase equilibria for inorganic/water mixtures typical of atmospheric aerosols; when organic species are present,...
