Avoiding Embrittlement with the H836EN
November 22, 2022
In 2013, as the eastern span replacement of the San Francisco-Oakland Bay Bridge was drawing to a close, 277 vertical steel rods to improve the seismic stability of the replacement were tested under tension using three-inch-diameter bolts. Within two weeks, 32 of the steel rods had snapped. 277 of these rods were used in the $6.5 billion construction project, but only 96 were accessible. Metal testing suggested hydrogen embrittlement during the manufacturing of the rods may have caused the failures. Thankfully, this was able to be corrected before the bridge opened, but it was a major setback in the construction.Read More…

All About Aluminum: The New H836EN
October 5, 2022
Once more expensive than gold, aluminum has not lost its value over the years, only its price tag. Thanks to revolutionary methods of production largely developed in the late 1800s, the price of aluminum dropped from $34 an ounce in 1852 ($1,276 in 2022 dollars) to just $0.09 an ounce today. As a low-density, high-strength, corrosion-resistant metal, aluminum's usefulness has led to incredible consumption in many industries from transportation to packaging.Read More…
In this application note, you will learn how the combination of GC×GC and HRTOFMS resulted in excellent quantitative PCP data.

Human vs Machines: Hardness Testing with the AMH55
June 22, 2022
Does automated hardness testing software really provide that much of an advantage over manual methods? LECO's Cornerstone-based AMH55 system takes the human variance out of the process, making it fast, precise, and accurate, but just how much variance is actually involved? LECO decided to put it to the test, pitting seven humans of varying metallographic experience against the AMH55.Read More…

Protein Analysis – Dumas vs. Kjeldahl
May 17, 2022
A Small Overview and Comparison
The protein content in food and feeds is one of the parameters that are commonly analysed within most routine control samples in a food laboratory. Generally, the two most used reference methods/technologies are the wet chemistry method after Kjeldahl and the combustion method after Dumas.Read More…
Year after year, the popularity of juice continues to rise. As consumers become more health- and environmentally-conscious, juice has risen to the forefront as a sustainable, vegan, and nutritious beverage option. It certainly doesn't hurt that with the pandemic, people have shifted to entertaining at home and making their own mixed drinks with juices as mixers. But how does juice actually hold up to nutritional demands?Read More…
Have you seen the article in the latest eFoodLab issue about MOSH/MOAH analytics?
In this interview Dr. Susanne Kühn from our customer Kirchhoff Institute describes how she uses LECO´s GC×GC-BT-TOF-MS for the characterization of the MOAH fraction. She describes why GC×GC enables a more detailed examination of the MOSH and MOAH fractions. Interested?
