Width Based Characterization of Chromatographic Peaks: Beyond Height and Area
TL;DR: In this paper, the authors focus on situations where WBQ is effective while height/area-based linear calibrations fail, e.g., when the detector is in a nonlinear response region, the data system is saturated, causing clipping/truncation of the signal, or the detector signal is not a single-valued function of concentration, as when a fluorescence signal goes into the self-quenched domain.

Sequential ion chromatography and conversion system
TL;DR: In this paper, the authors compared the performance of two conductivity detectors, one conductivity detector and a second conductivity detection detector, and provided additional information about the analytes.
Journal ArticleDOI
Cavity-enhanced absorption measurements across broad absorbance and reflectivity ranges.
TL;DR: It is shown that a small aperture in the entrance mirror greatly improves light throughput without significant departure from the theoretically predicted amplification of absorbance; such simple modifications result in real improvement of detection limits, even with mirrors of modest reflectivity and inexpensive detectors.

TL;DR: A DeHavilland DHC-6 Twin Otter was deployed in Tampa, FL to measure aerosols and primary and secondary trace gases in support of the Bay Regional Atmospheric Chemistry Experiment (BRACE) as discussed by the authors.
