The recent geo-political climate has increased the necessity for autonomous, chip-sized, lightweight, air sampling systems which can quickly detect and characterize chemical, biological, radiological, nuclear, and high explosive (CBRNE) hazardous materials and relay the results. To address these issues, we have developed a self-powered 3-D chip architecture that processes air to produce concent...

Capillary electrophoresis (CE) is usually off-line combined with an adsorption/desorption method to analyze gaseous or atmospheric samples. Here, we demonstrated direct sampling in the air of CE. The inlet end of a fused silica capillary filled with a pH 7.2 phosphate buffer was placed in the air for absorbing gaseous or volatile components, while the outlet end was immersed into a buffer vial ...

background: nanotechnology is a new approach that has been lionized in recent years. one of its applications is its consumption as an absorbent. in this study, the single-wall carbon nanotubes (swcnts) were used as an absorbent for sampling benzene in the air. materials and methods: for this study, swcnts manufactured by iran and skc’s activated charcoal were used for sampling benzene vapors. p...

Although several air sampling devices for identifying and enumerating airborne microorganisms are commercially available, each poses some limitations. The aim of this study was to evaluate air pollution fungi using three such samplers: SAS Super 100, Microbiological Air Sampler (MAS) 100, and Air IDEAL. Mycological air was taken from the cellars of a 17th-century church in Siemiatycze, Poland, ...
