TL;DR: In this article, the authors describe the direct measurement of soluble ionogenic atmospheric gases by a suppressed conductometric capillary electrophoresis separation system (SuCCESS), where a small circular wire loop is incorporated at the sampling end of a fused silica capillary located immediately at the tip in the same plane as the capillary.

TL;DR: In this paper, the maximum permissible sample throughput is a function of the electric field strength, capillary length and injection volume, and the relation between the various parameters is theoretically and experimentally discussed.

TL;DR: A simple, fast and sensitive light-emitting diode (LED)-based photometric method for the differential determination of ppb-ppm levels of As(III) and As(V) in potable water in the presence of ppm levels of phosphate was developed.

TL;DR: In this article, the design and characteristics of a dynamically growing and falling liquid drop based optical detection system are described for use with flow injection analysis (FIA), and several aspects of the analytical potential of a liquid drop as an optical cell are demonstrated by the detection of sulfate through the precipitation reaction between barium ion and sulfate ion in an FIA system.

TL;DR: In this paper, a study was conducted to measure hydrogen peroxide from three sources: (1) zero air in the presence and absence of common interferences, (2) steadystate irradiations of hydrocarbon/NO/sub x/ mixtures, and (3) ambient air.
