When the TruMac® Macro Determinator at the Southern African Grain Laboratory (SAGL) needed to be replaced, laboratory manager Jolanda Nortjé returned to LECO for an updated solution. For the past twenty years, LECO had been providing the SAGL with excellent service support, and their TruMac and previous nitrogen analyzers had been LECO products they were very satisfied with. At the end of 2019, trusting LECO again, the SAGL purchased a LECO FP928 to replace their TruMac.

Why do you use the sample container that you use? Is it something you've ever thought about? Sample containers and crucibles are both wonderfully simple, to hold your sample without influencing the analysis, and wonderfully complex... to hold your sample without influencing the analysis.

But are you using the best container for your type of sample?

There’s coal and then there’s coal, and Santa Claus knows the difference. When preparing coal for the stockings of naughty boys and girls on Christmas Eve, Santa is not about to waste high quality, high-carbon material on children who have been bad. But while Santa is magic and can tell in an instant which coal is appropriate, how can those of us not lucky enough to work out of the North Pole determine our coal quality?

Did you catch our recent article on Food Navigator? Nitrogen content in food materials is necessary to measure when determining the total protein content. This measurement of nitrogen content can be performed using a classical wet chemistry method, but this tends to be a slow and tedious process. The combustion-based Dumas method has gained popularity in recent years as it significantly increases laboratory productivity. Yet when the sample has a low level of nitrogen it can be challenging to analyze. Examples of these hard-to-analyze samples include dry corn starch, NDIN filter bags, nutritional drinks, and beer. How can the combustion method be optimized to accommodate these lower-level nitrogen samples?

Our innovative analytical instrumentation provides users with solutions for a wide range of applications. We want to help your lab succeed, which is why we share examples of the processes, methods of analysis, and results our instruments can obtain in the form of application notes. We want our current and potential customers to feel at ease with our instrumentation in the lab, and our application notes highlight the right instrument for each specific application.

Quickly and easily analyze your most challenging food samples with our solutions for total protein and nitrogen determination—the FP828 and FP928. 

Our popular 928 Series enables you to analyze macro samples with features that streamline your analysis. The latest model to enter our lineup, the CNS928, allows for the simultaneous analysis of carbon, nitrogen, and sulfur from one sample in agronomy and agricultural materials. The CNS928 maintains the core capabilities and performance of previous generations of LECO macro combustion instruments while introducing key improvements in throughput, uptime, and reliability.

Hear from our Organic Product Manager, Mason Marsh, as he discusses our solutions for carbon/nitrogen analysis and moisture determination in food, feed, and agricultural samples. In his interview with FoodQualityNews, he highlights the importance of nitrogen analysis in food and feed and how two of our products, the FP928 and FP828, will help user's achieve better productivity in their analysis with fast, reliable results.

We’re always looking for ways to improve your lab experience, and this means designing our products to help solve your lab’s biggest challenges. Our latest generation of thermogravimetric analyzers, the TGA801, introduces a number of improvements best suited for YOU and your analysis. The TGA801 is ideal for determining multiple constituents such as moisture, ash, volatile content, and LOI in a variety of organic, inorganic, and synthetic materials.
