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.

Pesky Pesto Peculiarities and GC×GC Analysis

April 13, 2022

Pesto can trace its roots back to ancient times, though it really only started taking off in North America in the 1980s and 90s. Though the primary base is consistent, with pine nuts, basil, and olive oil, individual recipes vary. As canned and bottled pesto became more accessible, individual manufacturers developed their own unique flavor profiles. While these recipes are usually trade secrets, the power of GC×GC TOFMS can tease apart some of the differences.

Calming Crude Oil with the CHN828

March 18, 2022

The price of crude oil is one of the great drivers of our economy. At a minimum, the price of all goods includes costs of transporting them from manufacturer to consumer. But the price of crude oil and other oil materials can feel fickle, increasing and decreasing with supply or demand or even just market sentiment. Natural disasters or humanitarian crises can drastically impact availability or demand, sending prices hurtling skyward or crashing down. No refinery can control the entire market. All a refinery can do is operate their facilities in the most efficient and optimized manner. Doing that, however, requires an accurate way to monitor their process.
