Iron and LECO: 85 Years of Analysis

Elements Newsletter recently published an infographic of all of the metals mined from the earth in 2019, and the numbers were staggering. 3,248,814,334 tons of metal were mined, of which 3,040,000,000 tons were iron ore. Nearly 94% of all of the metal mined in 2019 was iron, and nearly that percent of the iron has been, in some way, touched by LECO.

Vertical vs Horizontal Furnaces: The Dumas Method for Protein Determination

Over the last thirty years, the Dumas combustion method for analyzing protein content in food has been gaining popularity against the classic Kjeldahl wet chemical digestion and titration method. The Dumas method has several advantages over the Kjeldahl method: it is much faster, with much lower operating costs, no real safety issues, and no toxic waste produced. However, there is a debate over which of the two main approaches to the Dumas method is better: a vertical or a horizontal combustion furnace.
