Automated Phase Analysis in FGD Gypsum

TGA-press-release-400x200

Full Phase Analysis with an automated Macro Thermogravimetric System

Complete Phase analysis is general a difficult task that requires normally different analytical methods and technologies. A special application for the LECO TGA701 is shown here that delivers the right results with highest precision and accuracy.


The LECO TGA 701 is a universal instrument that determines a huge variety of parameters from different analytical fields. 19/38 analysis can be performed simultaneously in one run, fully documented with highest precision and accuracy. The crucibles can be reused many times so a macro analysis with sample weights of 1-5 g can be done with highest user convenience and sample throughput.

Determination of:

  • Gypsum (CaSO4 2 H2O)
  • Hydroxides Ca(OH)2
  • Moisture
  • Sulfite (CaSO3 1/2H2O)
  • Limestone (CaCO3)

And 1000 more applications in the “cement” market. LOI in clinker, Moisture/Volatiles/Ash in coal/coke and more…
Beside the building industry field the TGA701 is well known in many other analytical fields like moisture/ash in food, fiber volume determination in carbon reinforced plastics or moisture/ash/volatile determination in coal and coke.
