The TGA: Macro and Micro
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…
Folded Flight Path®: Ten Years of High Resolution
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…

Thermogravimetrically Testing Biomass
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…
