Journal ArticleDOI

Cobinamide chemistries for photometric cyanide determination. A merging zone liquid core waveguide cyanide analyzer using cyanoaquacobinamide.

TL;DR: It has been inexplicable how trace amounts of cyanide are sensitively measured by this reaction, and it is shown here that even with excess OH(H(2)O)Cbi(+), (CN)(2)CBI is formed first due to kinetic reasons; this implies that CN(H (2) O)CBi(+) will itself be a better reagent.
Journal ArticleDOI

Continuous automated measurement of hexavalent chromium in airborne particulate matter.

TL;DR: An automated continuous instrument for the collection and measurement of aerosol Cr(VI) is described, which is portable for facile field deployment and permits fully automated rapid determinations at a very low analysis cost per sample.
Journal ArticleDOI

Admittance Detector for High Impedance Systems: Design and Applications

TL;DR: An admittance detector for high impedance systems (small capillary bore and/or low solution specific conductance) that provides optimum response to conductance changes in capillaries ≤20 μm in bore and shows applications of the detector in electrophoresis and sensitive detection because of efficient electrostacking.
Journal ArticleDOI

Speciation-Capable Field Instrument for the Measurement of Arsenite and Arsenate in Water

TL;DR: Speciation analysis data from well water samples analyzed by this method agree well with HPLC-ICPMS measurements in a different laboratory, and robustness was confirmed for total As using three types of certified natural water samples.
Journal ArticleDOI

Rapid point of care analyzer for the measurement of cyanide in blood.

TL;DR: A small amount of ethanol added to the top of the blood was found to be the most effective means to prevent frothing during aeration and Bubbling air through the blood-acid mixture was found effective for mixing of the acid with the sample and the liberation of HCN.
