Journal ArticleDOI
Thin layer distillation for matrix isolation in flow analysis.
Patrick J Mornane,Jeroen van den Haak,Terence J. Cardwell,Robert W. Cattrall,Purnendu K. Dasgupta,Spas D. Kolev +5 more
TL;DR: The TLD technique should be an attractive approach for online analysis of volatile chemical species in 'dirty' samples, especially for volatile analytes of higher molecular mass.
Journal ArticleDOI
A continuous film-recirculable drop gas-liquid equilibration device. Measurement of trace gaseous ammonia
Zhang Genfa,Purnendu K. Dasgupta +1 more
TL;DR: With a fluorometric flow injection analysis system harnessed to measure ammonia with such a collector, the limit of detection for a sample drawn for 18 min at 200 mL/min was 4.5 parts per trillion by volume, with the linear range extending up to 30 parts per billion.
Journal ArticleDOI
A Diffusion Scrubber for the Collection of Gaseous Nitric Acid
TL;DR: A diffusion denuder with a thin anion exchanger membrane tube as the collecting element and with a scrubber solution flowing in a narrow annular gap outside the membrane is described in this paper.
Journal ArticleDOI
Study of transition metal ion-S(IV) systems
TL;DR: In this article, it was shown that metal sulfite compounds probably do not play any significant role in stabilizing sulfur (IV) in droplet solutions in the atmosphere and that rapid redox reactions occur and under some conditions the sulfur may be quantitatively converted to dithionate.
Journal ArticleDOI
A cold plasma dielectric barrier discharge atomic emission detector for atmospheric mercury
Mahitti Puanngam,Mahitti Puanngam,Shin Ichi Ohira,Fuangfa Unob,Jian-Hua Wang,Purnendu K. Dasgupta +5 more
TL;DR: An automated atmospheric elemental mercury analyzer based on the dielectric barrier discharge (DBD) atomic emission technique was developed and applied to the determination of atmospheric mercury in two different locations.
