April is all about Thermogravimetry, short TGA:
The Thermobalance – Universally Applicable for Many Materials
Thermogravimetry could always be used universally and therefore did not exclude any material. NETZSCH – stemming from high-temperature applications such as ceramics, glass, and metals – had to realize at the end of the 1980s that rapid economic growth was also occurring in other industries, including organic chemistry, pharmacy, medical technology, biotechnology, the food industry and, last but not least, the all-important plastics industry. To accommodate all these applications, a smaller, faster and – as we “NETZSCH people” say – low-temperature thermobalance was needed quickly.
Some Insights into the NETZSCH Instrument Nomenclature
By the end of the 1980s, NETZSCH had adapted to the fact that ‒ in view of invasive plastics technology, medical/pharmaceutical technologies, and application possibilities in the food and feed industries; in short, the “world of organics” ‒ we had to move into the lower realms of temperature ranges in order to hold the “leading position” in thermal analysis but also to grow.
Therefore, already in 1987, the first “non-400 thermoanalytical instrument”, the DSC 200, was introduced as a testing instrument for plastics. Thus, the “low-temperature instrument series”, as it was called from then on in NETZSCH cycles, was born. And, as it soon turned out, this supposedly “low-temperature 200 series” expanded to a temperature range of no less than 1000°C! ?
Thus, in 1989, the first NETZSCH TG 209/2/C was born; in its nomenclature, the “last digit”, 9, has always been (and still is) reserved for thermobalances. The “2” represents the temperature range that was defined to 1200°C, and was only undercut by the “1” for coolable furnace systems. Numbers 3, 6, 7, and even 8 for one instrument, were assigned to the temperatures from 1500°C to ultimately 3000°C.
Back to the new balance and the unique success story of the TG 209 that conquered the world and also the hearts of customers like no other balance. The decisively advantageous features of this small, fast thermobalance have prevailed and proven both worthwhile and successful over the entire 30 years to this day.
Today: Vacuum-Tight Thermo-Microbalance for the Highest Demands
After the Iris®, Tarsus® and Nevio® models, it’s above all the TG 209 F1 Libra® with its fast ceramic furnace to 1100°C that enjoys lasting popularity today. This is because NETZSCH developed the TG 209 F1 Libra® thermobalance based on more than 60 years of experience in thermogravimetry. With this instrument, analyses can be carried out even faster, more accurately and over an expanded temperature range.
Advantages at a glance:
- Top-loading weighing system (chimney effect, balance protection)
- Purge-gas-rinsed, thermostated and high-resolution microbalance (0.1 µg)
- Fast, water-cooled ceramic furnace in Al2O3 protective tube
- Vacuum-tight (with AutoVac) and triple MFC for gas purging and exchange
- Can be perfectly coupled to all imaginable gas analyzers: Solutions for QMS, GCMS and FT-IR couplings directly from NETZSCH through a single source with joint control and software solutions
By the way: The children of our Chinese colleagues have also been busy with the TG 209 F1 Libra® and have created an illustration for it that we’ve included in this year’s calendar for the month of October:
