Subject:
adrenal cortex hormones; aerosols; bioavailability; caffeine; drugs; drying; ethanol; geometry; glass transition temperature; ingredients; particle size; particle size distribution; propionic acid; scanning electron microscopy; solubility; statistical analysis; thermal analysis
Abstract:
... The aerosol performance, physical properties and formation process of two corticosteroids (beclomethasone dipropionate and fluticasone propionate) and caffeine (active pharmaceutical ingredients: APIs) from ethanol-based pressurized metered dose inhaler solution formulations, containing various ethanol fractions, were evaluated using cascade impaction, thermal analysis and scanning electron micros ...

Source:
Analytical chemistry 2015 v.87 no.23 pp. 11887-11892
ISSN:
1520-6882
Subject:
aerosols; caffeine; cellulose; gases; ionization; ions; pyrolysis
Abstract:
... The design and operation of an inexpensive, miniature low-temperature plasma ion source is detailed. The miniature low-temperature plasma ion source is operated in a “flow-through” configuration, wherein the gaseous or aerosolized analyte, caffeine or pyrolyzed ethyl cellulose, in a carrier gas is used as the plasma gas. In this flow-through configuration, the sensitivity for the caffeine standard ...

Subject:
aerosols; air; air quality; alkanes; atmospheric chemistry; caffeine; cannabinoids; cleaning; gas chromatography; hospitals; mass spectrometry; nicotine; pollution; polycyclic aromatic hydrocarbons; samplers; soil; vapors; Algeria
Abstract:
... Indoor environments are affected by a number of organic contaminants, whose concentrations can exceed by orders of magnitude those found outdoors in external air. At this regard, polycyclic aromatic hydrocarbons (PAHs) deserve a special concern. PAHs occur in the air both in the gaseous and particulate forms; they are associated to fine aerosols and soil dust, and deposit on surfaces. Nonetheless, ...

acetone; acrolein; aerosols; air; alkanes; benzaldehyde; caffeine; carbon; formaldehyde; nicotine; nitrogen oxides; organic matter; ozone; phthalates; pollution; polycyclic aromatic hydrocarbons; toxic substances; Mediterranean Sea
Abstract:
... Particulate polycyclic aromatic hydrocarbons, n-alkanes and polar organic compounds were investigated in the marine atmosphere of Southern and Eastern Mediterranean Sea, in the frame of the scientific cruise of Urania ship between 27 July and 11 August 2013. The PM10 fraction of aerosol to which most organic substances are associated, were collected daily; contemporarily, gaseous regulated toxican ...
