TGA-2000A-EB Series
(Patented)

Multi-sample Thermogravimetric Analyzer With Additional External Balance For Increased Throughput

The TGA-2000A-EB Series is a general purpose moisture, volatile-matter, ash, fixed carbon and loss on ignition (LOI) analyzer, etc ..., It can be used to analyze a wide variety of organic and inorganic materials like: cement, coal, coke, iron ore, bauxite, nickel and other ores, gypsum, food, feed, snacks, dough, wheat, flour, biomass, graphite, soil, plastics, fertilizers, rubbers, used engine oil etc ...

Brief technical specifications:

• Temperature range: 50 ~ 1000 ºC ±1 ºC
• Sample Size: 0.1 ~ 20 grams
• Balance resolution: 0.0001 grams
• Number of Samples: 19 simultaneously plus 1 reference crucible to compensate for crucibles buoyancy, models with different numbers of samples available (11, 15, 19, 23), models with double carousel (38 or 46 samples), large ceramic crucibles for non homogeneous samples
• Weight Loss/Gain Range: 0 ~ 100 %

Navas Instruments TGA-2000A-EB's come standard with these important differences:

• Temperature regulation is plus/minus one degree Centigrade
• Extremely robust mechanical design
• Exceptional and unsurpassed reliability
• Complete brand name digital precision balance of 0.1 mg sensitivity with display
• Service, although seldom required, does not require highly-trained technicians, Navas Instruments provides service directly or with local dealers
• Parts are standard and generally available locally

This model is similar to TGA-2000A or TGA-1000 series but with an additional external balance used to obtain the initial weights of crucibles, samples and/or covers outside furnace during the analysis time for increased throughput.

The TGA-2000A-EB series uses only one PC to manage both the external balance and the instrument at the same time.
This configuration allows from 20 to 60% more throughput than a regular furnace.

Operation:

During the analysis of the first batch of samples, the initial weights of crucibles, samples and/or covers are obtained on external balance and placed in plastic trays or removable carousels ready for next analysis, thus eliminating dead loading time.

1. When furnace reaches 60-70 ºC (after cooling, instead of 34 ºC ) the pre-weighed crucibles with samples are moved by hand from plastic tray to carousel.
   
2. Operator presses the start button using the mouse in the TGA software and the instrument starts immediately analyzing (No need to take the initial weights of crucibles & samples, saving 20 or more minutes of loading time).
   
3. Any number of trays with pre-weighed crucibles and samples can be prepared during furnace analysis time.

The TGA weights station software can work also with multiple TGA units in a networking configuration.
There are also dual TGA-2000A-EB models with one (1) PC that controls the two (2) instruments and one (1) external balance at the same time.
Any number of TGA units can be connected in a network for customers with large numbers of samples to analyze.

Different sizes of ceramic crucibles can be used depending on the size of the sample to be analyzed
