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…

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…
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.

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…
The first Time-of-Flight (TOF) mass spectrometer was proposed in 1946, and the design has been refined and iterated upon every since.With an unlimited mass range visible in each spectrum and a high spectral generation speed, the advantages of TOF mass spectrometry were immediately clear. Though the instruments improved, they did eventually hit physical limitations that restricted the resolving power. More…

So many factors go into the quality and characterisation of plants and biomass, but many thermogravimetric analyses take so much time. Drying, ashing, and weighing multiple samples takes effort and care just to control for atmospheric effects, much less to actually get precise results that can then be used to analyse the quality and structure of the plants. LECO's TGA801…
