Protein-Rich Pet Food

February 24, 2023

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.

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.
