TL;DR: The present paper shows that there are remarkable advantages to be gained from forming a film of the sample solution on a wire loop and using the loop itself as the high-voltage electrode to perform electromigration from a very small sample volume.

TL;DR: In this article, the authors used a novel AlGaN light-emitting diode (LED) fabricated on a sapphire substrate that has peak emission at 291 nm, and demonstrated that a compact detector based on this LED and an off-the-shelf gated photodetection module can provide an LOD of 0.4 nM, thus providing a basis for convenient early warning detectors.

TL;DR: In this article, an electroosmotically pumped capillary format sequential injection analysis system with a membrane sampling interface for determination of gaseous analytes is introduced, and the applicability of the system has been demonstrated by the determination of ammonia at the parts per billion level.

TL;DR: In this work power functions applied to chromatographic data are discussed in the context of (a) complex separation problems, (b) 2D-HPLC separations, and (c) post-column reaction detectors.

TL;DR: Particle deposition characteristics of several diffusion scrubber (DS) designs of annular geometry were studied and a straight inlet geometry was selected for further performance evaluation as mentioned in this paper, and extensive performance tests were made with the new geometry DS; Nafion® membrane based DS devices are recommended for the measurement of H2O2 and HCHO.
