Instrument Updates Available Online

Many of LECO's instruments take advantage of powerful proprietary software that is constantly being improved and updated. While LECO's Cornerstone® brand software can check for updates itself if the instrument is connected to the internet, not all instruments can be connected, for privacy or security reasons. If you ever want to check your software version, you can go to LECOSoftware.com.

Seeing Clearly through Lucite with the MX-Series

If all you need for your mount is a uniform shape to hold your sample, Bakelite or epoxy would work just fine. It's simply a matter of finding the mounting material that works best with the sample material. But if you need a mounting material that lets you see the sample mounted within, there is no better choice than Lucite.

Moisture Determination in Iron Ore with the TGM800

When the Kaunis Iron Mine opened in Sweden, it was the newest in one of Sweden's biggest industries. The mine contracted with Degerfors Laboratory (D-LAB) for their iron analysis. Before analysis could be run on the samples, however, the ore had to be dried and moisture levels measured. D-LAB had a problem: their current moisture determination methods used a manual balance that could only handle one sample at a time, requiring a technician's attention every five minutes. The ISO 3087:2020 method used was also a problem, as a single run could take more than 5 hours to complete. The lab turned to LECO for a solution.

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.

Revising the Standards: Volatile Matter in Coal and Biofuels

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.

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.
