Iron and LECO: 85 Years of Analysis

October 22, 2021

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.

Revising the Standards: Volatile Matter in Coal and Biofuels

October 15, 2021

Coal and other biofuels are no different from every other substance that can be bought and sold: the quality of the material plays a huge role in the determination of the price. With coal and other solid fuels, the amount of volatile matter is the main factor in quality, as this determines the burning rates of the fuel. While the volatile matter value does rely on the type of fuel and moisture content of said fuel being tested, it also varies based on the heating rates used in the tests to determine the value.

Death, Disease, and Mummies: A Virtual GC/MS Symposium

October 8, 2021

For many, fear of the unknown can be paralyzing. A smell, a taste, an object that cannot be identified... for most people, it is a warning to stay away.

For mass spectrometrists, it is an invitation.

To celebrate the season, LECO is taking a look at the spookier side of mass spectrometry with a virtual symposium celebrating science beyond the grave.

Vertical vs Horizontal Furnaces: The Dumas Method for Protein Determination

September 24, 2021

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.

Building Strong Foundations Webinars

September 3, 2021

No matter where you are in the urban landscape, you are never more than a few feet from cement. Cement forms the basis of virtually the entire world’s infrastructure. It is an impressively cheap binder that enables a wide variety of building materials. Despite its ubiquity, it is a surprisingly complex mixture of a balance of ingredients such as lime, silica, alumina and more. Knowing what is in your cement is a fundamental check of its quality and strength.

Towards an Even Better Tasting Veggie Burger with GCxGC-MS

August 27, 2021

Sustainability is on everybody’s mind these days. Companies want to create products that are better for the environment and consume fewer resources. Unilever is no exception. This forward-thinking flavor company has recently been pushing to develop new and delicious plant-based protein substitutes that are more sustainable than meat-based protein but no less healthy (or, preferably, even more healthy!). However, as Unilever scientists Hans-Gerd Janssen and Ed Rosing explain, nature made a pretty delicious protein in the form of meat, with a very distinct flavor and mouth-feel. Creating a substitute isn’t easy.
