Automating Better Water: The TGA and Water Treatment

May 13, 2022

Clean, safe water is a cornerstone of life itself, and the ability to properly process and treat wastewater is a key component in environmental preservation. As such, water treatment plants such as Veritas S. p. A (Veneziana Energia Risorse Idriche Territorio Ambiente e Servizi) are a critical part of water infrastructure, and the analytical methods they use are a critical part of water treatment.

Thermogravimetric: Automated

April 1, 2022

Traditional thermogravimetric analyses such as loss-on-drying or loss-on-ignition techniques are long processes with many manual steps as samples are measured and transferred and re-measured to determine the loss. Every touch increases labor requirements and the chance for operator error. But there's a better way.

Moisture Determination in Iron Ore with the TGM800

November 9, 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 used 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.

Revising the Standards: Volatile Matter in Coal and Biofuels

October 15, 2021

Coal and other biofuels are no different from every other substance that can be bought and sold: the quality of the material plays a huge role in the determination of the price. With coal and other solid fuels, the amount of volatile matter is the main factor in quality, as this determines the burning rates of the fuel. While the volatile matter value does rely on the type of fuel and moisture content of said fuel being tested, it also varies based on the heating rates used in the tests to determine the value.

Building Strong Foundations Webinars

September 3, 2021

No matter where you are in the urban landscape, you are never more than a few feet from cement. Cement forms the basis of virtually the entire world’s infrastructure. It is an impressively cheap binder that enables a wide variety of building materials. Despite its ubiquity, it is a surprisingly complex mixture of a balance of ingredients such as lime, silica, alumina and more. Knowing what is in your cement is a fundamental check of its quality and strength.

Slice Time off your Meat Moisture Analyses with the TGM800

August 13, 2021

As with all foodstuffs for human consumption, meat is highly regulated. Determining its makeup is essential to confirming a safe product. The faster regulatory analyses can be performed, the quicker you can confirm the quality of your product and maintain production speed.

Determining the moisture content of meat is one such analysis that helps identify the quality and safety of the meat in question. Moisture content can control the texture, taste, and microbial stability of the meat. It also determines the level of retained water, additive solutions for flavoring, and the leanness of meat.

Gypsum and the TGA: Analyzing FGD Solids

July 23, 2021

The thermogravimetric analyses of the TGA801 and its predecessors can do more than measure organic materials. With its ability to handle large, gram-sized samples, the TGA801 has become an invaluable tool for the monitoring of industrial byproducts, such as flue-gas desulfurization (FGD) solids.

The TGA: Macro and Micro

May 21, 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).
