10 Steps for Measuring pH Accurately and Consistently is an infographic created by Reagecon which details the most important steps to measure pH. From selecting an appropriate measuring system right through to the role of accreditation in pH measurement, this...
This paper by John Barron, Colin Ashton and Leo Geary of Reagecon gives a comparison of Reagecon COD vials and Hach COD vials when used with the Hach DR/2010 photometer. Details on the reagents and apparatus, procedure, test samples, results, accuracy and...
Introduction Virtually every aspect of society is supported in some way by analytical measurement. There are innumerable reasons for making these measurements, for example: in-process and final inspection or ‘quality control’ of manufactured products; supporting...
This short video provides viewers with an overview and short summary of Analytical Volumetric Solutions, Titrants and Indicators.
The principle of all titrimetry involves the determination of the quantity of the reagent of known concentration the (titrant), that is required to react completely with an unknown analyte. Volumetric titrimetry involves measuring the volume of the solution of known concentration the (titrant) consumed, gravimetric titrimetry measures the mass of the reagent consumed and coulometric titration measures a direct electrical current of known magnitude that consumes the analyte. In coulmetry, the time it takes to complete the electrochemical reaction, is the measurement.
This short video provides viewers with an overview and short summary of Atomic Absorption Standards.
There are two main types of Atomic Absorption Spectrometry, Flame Atomic Absorption Spectrometry and Graphite Furnace Atomic Absorption Spectrometry. There are advantages both technical and commercial, attributable to each one.
Atomic Absorption Standards are just one of the many product ranges provided by Reagecon and this paper provides details on the two main types of Atomic Absorption Spectrometry (AAS), Flame Atomic Absorption Spectrometry (FAAS) and Graphite Furnace Atomic Absorption...
Azo Dye Metabolite Standards are offered by Reagecon as ready to use, single and mixed compounds which have been dissolved in a number of matrices to facilitate testing requirements. These standards can be viewed in our Physical and Chemical Standards Compendium or in...
