Journal ArticleDOI
Porous membrane-based diffusion scrubber for the sampling of atmospheric gases
TL;DR: In this paper, a diffusion scrubber, employing a porous fluorocarbon membrane as the sampling tube and with a scrubber solution flowing into a narrow annular space exterior to the membrane, is described.
Journal ArticleDOI
Green analyzer for the measurement of total arsenic in drinking water: electrochemical reduction of arsenate to arsine and gas phase chemiluminescence with ozone.
Mrinal Kumar Sengupta,Maather F. Sawalha,Shin Ichi Ohira,Ademola D. Idowu,Purnendu K. Dasgupta +4 more
TL;DR: In this paper, a matrix-isolated reaction chemistry based measurement of arsenic in water down to submicrograms per liter levels in a system that requires only air, water, electricity, and dilute sulfuric acid, the bulk of the latter being recycled.
Journal ArticleDOI
Simultaneous Electrodialytic Preconcentration and Speciation of Chromium(III) and Chromium(VI)
TL;DR: A new electrodialytic separation concept that permits simultaneous matrix isolation, preconcentration, and chromium speciation is presented and it is shown that effects of salinity can be eliminated with proper membrane functionalization and receptor optimization.

Apparatus and method for flow injection analysis
TL;DR: In this article, an electroosmotic pump having a grounding joint was used to accelerate a carrier for flow injection analysis at a controllable flow rate, where a sample was added to a liquid carrier stream to form a sample zone.
Journal ArticleDOI
Fiber optic sensor for simultaneous determination of atmospheric nitrogen dioxide, ozone, and relative humidity.
TL;DR: A novel optical sensor for the simultaneous measurement of atmospheric nitrogen dioxide, ozone, and relative humidity, using a transparent backing thin layer silica gel chromatographic plate impregnated with 8-amino-1-naphthol-5-sulfonic acid as the collection/sensor element is described.
