John Barron

John Barron, is an Irish based chemical metrologist who is a leading world authority on the development, manufacture, application and distribution of chemical and physical standards and reference materials. He is the founder, chairman and CEO of Reagecon, the largest producer of such standards worldwide. The company produces in excess of 10,000 of such products and John Barron has either been lead scientist or been involved with the research and development team that developed all of these. The products developed cover a wide range of areas that include standards for Electrochemistry, Spectroscopy, Total Organic Carbon, Cation and Anion standards and a wide range of Organic standards. They also include physical standards covering diverse areas such as Viscosity, Density, Colour, Refractive Index, Osmolality and other niches within physical chemistry. Included within the organic standards are such products as Volatile Organics (VOCs), Polyaromatics (PAHs), Pesticides, Phthalates and many others. In total the portfolio of products extends to 54 different families with more under development. John Barron has written and published substantial amounts of written material, has scripted and produced many webinars and has made presentations at conferences all over the world.

A Guide to Method Validation

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...

Analytical Volumetric Solutions, Titrants and Indicators

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.
