Measurement of atmospheric formaldehyde using a drop collector and in-situ colorimetry
(Gordon Breach Sci Publ Ltd, 1997-01-01)
A sensitive and affordable approach is described for the in-situ measurement of ambient formaldehyde. Air is sampled around a 100 microliter aqueous drop containing 3-methyl-2-benzothiazoline hydrazone. After a desired ...

Colorimetric determination of ammonia in air using a hanging drop
(Marcel Dekker Inc, 2003-01-01)
A simple and sensitive method for determining atmospheric ammonia (NH3), using a hanging drop, is described. A colorimetric sensor is composed of two optical fibers and the source of monochromatic light implemented was a ...

Construction and performance of a drop cell for the nephelometric determination of sulfur dioxide
(Elsevier B.V., 2003-02-01)
A nephelometric technique based on a liquid drop is described for the measurement of atmospheric sulfur dioxide. A 40-mul drop of barium chloride and hydrogen peroxide solution is suspended in a flowing-air sampling stream. ...

Localized ant colony of robots for redeployment in wireless sensor networks
(Old City PublishingPhiladelphia, 2014)
Sensor failures or oversupply in wireless sensor networks (WSNs), especially initial random deployment, create spare sensors (whose area is fully covered by other sensors) and sensing holes. We envision a team of robots ...
Fluorometric fiber optic drop sensor for atmospheric hydrogen sulfide
(Elsevier B.V., 1997-06-01)
A fluorometric technique based on a liquid drop excited from its interior by an optical fiber is described for the measurement of low concentrations of atmospheric hydrogen sulfide (H2S). A drop of alkaline fluorescein ...
