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.

A Fishy Analysis: FP828 and Protein Determination

March 10, 2022

eFOOD-Lab International – Interview with Express Micro Science

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.

Moisture Determination in Iron Ore with the TGM800

November 15, 2021

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.

Vertical vs Horizontal Furnaces: The Dumas Method for Protein Determination

October 20, 2021

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.

Microplastics: Seeing the Details with GC×GC

July 20, 2021

Microplastics are a ubiquitous presence in the world, found from Arctic snow to Antarctic ice and everywhere in between. 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.

The TGA: Macro and Micro

July 5, 2021

Thermogravimetric analysis (TGA) first started in the early 20th century, and while the technology has advanced, the basic principles remain the same. With TGA, the rate of change of reactions in the chemical and physical properties of materials as functions of temperature or time is what is used to assess the properties of the sample materials. Most TGA these days is done with either micro TGAs (using milligram-size samples) or macro TGAs (using gram-size samples).
