Latest News and Application Notes

Unlike the detailed list of nutritional requirements for human food, pet food in North America must only report on four main values in their Guaranteed Analysis on the label: protein, fat, fiber, and moisture. Additional nutrients must be included if they are called out specifically on the label, but manufacturers can also voluntarily add more nutrients to provide consumers with more information or further demonstrate the nutritional value of their products. Surprisingly, one such voluntary "nutrient" that frequently appears on labels is "ash."  However, the presence of ash in the Guaranteed Analysis does not indicate the presence of literal ash in the food; instead, it explains the process through which the mineral content is determined.

Ever since its development in 1883, the Kjeldahl method of protein determination had been the standard in laboratories across the world. It wasn't until the 1990s that the Dumas method began acquiring a foothold. Though the Dumas method was technically older than the Kjeldahl, only recent technological developments have made it easily accessible to labs, and "easily accessible" is certainly one way to describe the modern Dumas method of protein determination, especially how LECO does it.

Most fasteners are essentially springs, and when these fasteners fail it is usually abrupt, "out of nowhere," and caused by fatigue. Fatigue failure is estimated to account for 80-90% of all fastener breaks. However, by its very definition, fatigue damage happens over time, due to repeated loading that stresses an already weakened location. ASTM E1823-10a, Terminology Relating to Fatigue and Fracture Testing, defines fatigue as: "The process of progressive localized permanent structural change occurring in a material subjected to conditions that produce fluctuating stresses and strains at some point or points and that may culminate in cracks or complete fracture after a sufficient number of fluctuations." Preventing fatigue failure is a critical part of engineering designs.

While plant-based proteins have been part of humanity's diet for centuries, it wasn't until the advent of the original textured vegetable protein (TVP) in the 1960s that it started becoming a viable replacement for animal-based protein sources in more mainstream diets. The first commercially available plant-based proteins would not be mistaken for animal-based protein sources and were largely of interest only to vegans, vegetarians, and pescatarians. 

Things have changed dramatically in the plant-based protein sector, especially in the last ten years. Meat-substitutes that looked, smelled, felt, and tasted similar to meat swept the market, and in an age where consumers are becoming more and more informed and interested in sustainability and stewardship of the planet, plant-based protein has risen as a viable alternative for about one in four consumers, those who consider themselves flexitarians.

Soil moisture is a strong indicator of the health and potential of soils in a field, but there is no set value that means soil is "good." The makeup of soil is just as important as the types of plants attempting to grow in said soil to know what levels of soil moisture are optimal for any given situation. Furthermore, nature has a nasty tendency to throw a curveball, knocking carefully balanced irrigation plans out of whack.

When you think of a sports competition, you may picture several athletes at the tops of their game duking it out for supremacy, whether on a pitch, a track, a course, a pool, or wherever else their sport takes them. But sport competitions can transcend humans challenging each other. The competition in the sports equipment industry is just as fierce as that between players.

It remains impossible to predict the future accurately, no matter how much we try. While market forecasts and trends tend to illustrate the future of products, reality always has a chance to throw a curveball. Between the global COVID-19 lockdowns suppressing most markets and a trend toward renewable energy sources, coal was expected to start decreasing in market value. Instead, a war between Russia and Ukraine and the lifting of lockdowns has actually driven a higher demand.

Pet ownership has increased over the last few years, when an explosive boom during the COVID-19 lockdowns showing no signs of stopping. Over 70% of American households have at least one pet, with most of those homes having at least one cat or dog. As pet ownership continues to rise, so too does the demand for pet food.

In the race between the tortoise and the hare, which style of instrument analysis is best for your lab? Slow and steady or fast and loose? Unlike the fable, however, there is no one-size-fits-all approach to elemental analysis, and that is precisely why LECO's instruments do not employ one-size-fits-all methods.

As global industrialization has increased, so too has global waste. Over 2.6 trillion pounds of waste are generated worldwide each year. Energy demands continue to grow year over year, and the Earth's population is looking toward greener solutions. Those 2.6 trillion pounds of trash may be waste now, but some of it may be suitable as biomass.
