A portable device for atmospheric flow tube-mass spectrometry (AFT-MS) could speed up drug screening at border control.

Since atmospheric pressure at sea level is equal to 14.7 psi then this means that a material's vapor pressure will be slightly greater than 14.7 psi at the material's BP.

Materials. Vapor retarders are rated by their permeance, ... (1/7000 lb.) per hour induced by a vapor pressure gradient between two surfaces of 1 in. of mercury.

It features all the components of the IGA-001 model in addition to anti-condensation protection feature rated to 50°C and an additional low range pressure sensor. The system can be integrated with a ...

The vapor-induced crystallization of an amorphous material often occurs with a sharp mass loss, caused by the lower surface area, surface energy, and/or void spaces in the crystalline phase.
