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.

Elemental Analysis, Separation Science, And Metallography News By LECO
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.

Express Micro Science (EMS) is the only food nutritional laboratory in Scotland, serving clients in food, leisure, agricultural, and pharmaceutical industries. For more than ten years, they've had constant, steady growth. But after they added protein determination to their services, they struggled with their instruments and results. Finally, in 2020, after five years of frustration, they chose to replace their old instruments with the LECO protein determinators.
Effective Analysis of Dairy Products
The analysis of dairy products is an important part of the LECO product portfolio for food analysis. LECO systems control the quality, food safety and nutrition facts of milk and dairy products.. Moisture/Ash/Protein determination, precise, fast, accurate in liquid and solid matrixes. Raw milk, cream, curt, milk powder or cheese – no special sample treatment with low analysis costs.

Lena M. Dubois' presentation discussing solutions to challenges faced in routine analysis and discovery work during aroma analysis in the food industry is now available as on-demand video.
GC-MS is widely viewed as the gold standard for biomarker discovery and identification in breath research. Multiple articles have been published utilising LECO GC-TOFMS and GC×GC-TOFMS showing typically:

LECO instruments analyse the quality, safety, and nutritional value of many foods and feeds – from raw foods to final consumer-ready products.
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 use d 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.

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. Determined to settle the question on which method is more precise and offers the most advantages, LECO chemists analyzed many sample types in both an FP828 and an FP928.

There are trillions of microplastic particles floating on surface water, and everyone from infants to adults are presumed to be ingesting anywhere from dozens to tens of thousands of these particles every day. But the science of microplastics, especially the incredibly tiny, potentially-cell-disrupting nanoplastics, is only just beginning. The effects of these microplastics isn't well known, largely because the scale of microplastics isn't well known. They are, by definition, difficult to see.
Unless you're looking in a second dimension.
