TL;DR: It is concluded that exposure of rats to well-characterized 1-μm aerosols of sodium sulfite at concentrations equivalent to amounts of SO2 of about 0.2 – 2.7 ppm results in responses of the rats that may be conveniently evaluated when sensitive enough toxicological indexes are quantitated.

TL;DR: In this paper, hydrogen cyanide at low ppbv levels is determined in the presence of several thousand ppmv H 2 S. The gases diffuse through a porous polyvinylidene difluoride (PVDF) tubular membrane into an NaOH absorber; the pH is then adjusted to 95-10, and the liberated HCN is selectively permeated across a tubular silicone rubber membrane into a NaOH absorber.

TL;DR: Limits of detection (LODs) are better than those previously observed with custom-synthesized dicationic agents and are readily attainable with a single-quadrupole mass spectrometer.

TL;DR: In this paper, the authors applied feedback-based flow ratiometry and the principle of compensating errors to potentiometric acid-base titrations and achieved high throughput with reasonable reproducibility (0.7% R.S.D.).

TL;DR: In this article, a universal and sensitive detection method for anion chromatography is described, where suppressed conductometric detection carried out with an NaOH eluent and an electrical suppressor, the eluite is transported through a microscale electrodialytic NaOH generator and a second conductivity detector.
