cou·lom·e·try

(kū-lom'ĕ-trē)
A titration technique in which the titrant is electrochemically generated. The Ag+ titrant in the chloridometer is commonly used to determine the concentration of chloride in the sample.

Easy maintenance means no standardization of reagent is required in coulometry. Operation is simple with an injection of the sample solution into the electrolyte-filled measuring vessel to obtain results.
The team has examined the interaction between surface plasmon resonance and nanofeatured surface structures for laser writers with sub-wavelength lithographic capabilities; innovative lipids found to dissolve or inactivate deadly viruses such as SAP, S, avian flu, etc.; and electrochemistry-based blood analysis instruments possessing break-through coulometry capabilities.
Replacing the chloride electrode whenever the result for selectivity control solution exceeded its 3 SD limit reduced the rate of falsely high (difference for ISE minus coulometry >10 mmol/L) results to 0.3%.
The layers were characterized with x-ray fluorescence (XRF), electrochemical stripping coulometry and atomic force microscopy (AFM).
For a detailed elucidation of the oxidation mechanism of the BC and PC and the reduction of their oxidation products, the spectral analysis (NMR or mass spectrometry) and coulometry are recommended for the future investigations.
coulometry. The reduction was thought to proceed by initial formation of the radical anion which subsequently dimerizes.
Easy maintenance eliminates the need for reagent standardization in coulometry. Operation is simple; the sample solution is simply injected into the electrolyte-filled measuring vessel, and results are obtained rapidly and accurately.
When combined with column switching, our approach is also more sensitive than other methods: its detection limit is four times lower than the latest reported detection limits for fluorometry (15) and coulometry (31).
Carbon coulometry is useful for the determination of total carbon (TC), total inorganic carbon (TIC), and total organic carbon (TOC) in samples where the measurable carbon level exceeds 10 [micro]g.
