TGA-1000, TGA-2000A and
TGA-2000A-EB Series (TGA for several applications)
Navas Instruments Thermogravimetric analyzers
allow the analysis of several samples simultaneously in the time it
takes to analyze one (1) sample.
TGA-2000A and TGA-2000A-EB
(TGA for coal, coke and other applications)
The
automatic crucible cover placement and removal system (patented) during the determination of volatile-matter makes the instrument fully
automatic and eliminates the risk of sample oxidation. It provides better
repeatability of the volatile matter results.
Below is an example of the
repeatability of the volatile-matter accuracy:

TGA-1000 (TGA for food,
animal feed, flour, wheat, dough, snacks, iron-ore, cement, bauxite, biomass,
oils, etc.)
This
TGA model can be upgraded to model TGA-2000A-EB (Model with additional external balance with increased output,
patented)
TGA-2000A-EB (TGA for food,
feed, flour, wheat, dough, snacks, iron ore, cement, bauxite, biomass,
oils, etc.)
The TGA with weights station server software (networking optional) allows to get the initial weights of crucibles and samples (and optionally crucible-covers) out of the furnace using an additional external balance while the furnace is analyzing and crucibles are placed in plastic tray ready for analysis.
With the TGA weights station server software no time is wasted in getting the initial weights, therefore, no furnace time is wasted.
In TGA without external balance it takes twenty (20) minutes TO GET INITIAL WEIGHTS of crucibles and samples inside the furnace, in our TGA it takes one (1) minutes TO MOVE CRUCIBLES AND SAMPLES FROM PLASTIC TRAY INTO THE FURNACE.
No need to cool to room temperature, only to 60ºC, therefore, save time in two directions (cooling and heating), saving 20 - 30 minutes.
The TGA-2000A-EB series uses only one (1) PC to control both the furnace operation and external balance at the same time.
