Journal ArticleDOI
Amperometric microsensor for water
TL;DR: In this article, a thin film of a perfluorosulfonate ionomer (PFSI) is supported upon two electrodes, and the positive electrode is composed of a noble metal.
Journal ArticleDOI
Applications of in situ detection with an auto-mated micro batch analyzer
TL;DR: In this paper, an automated micro batch analyzer (a.m.b.a.), a new batch-type microscale liquid-phase analyzer, called a micro-batch analyzer with a reaction chamber equipped with conductometric, potentiometric, fluorimetric and spectrophotometric sensors is introduced.
Journal ArticleDOI
Preconcentration/preelution ion chromatography for the determination of perchlorate in complex samples
TL;DR: The determination of perchlorate in complex matrices by ion chromatography (IC) with an online preconcentration and preelution technique is discussed and is highly effective in removing most of the matrix anions and was thus resistant to the interferences commonly encountered in a high ionic strength background.
Journal ArticleDOI
Trace gas measurement with an integrated porous tube collector/long-path absorbance detector.
TL;DR: Low cost, ready applicability to the measurement of different gases by merely changing the light source and chemistry, and high sensitivity makes this instrument attractive for both pedagogic and practical purposes.
Journal ArticleDOI
Measurement of atmospheric formaldehyde using a drop collector and in-situ colorimetry
TL;DR: In this article, a sensitive and affordable approach for the in-situ measurement of ambient formaldehyde is described, where air is sampled around a 100 microliter aqueous drop containing 3-methyl-2-benzothiazoline hydrazone.
