The TG 449 F3 Jupiter® is the workhorse for thermogravimetric analyses of a moderate to high sample weights from -150°C into the high temperature range of 2000°C. The vertical design with top-loaded samples ensures total protection of the balance, which is on the bottom, through accurate flow of the purge and protective gases in a natural vertical path to the top, with optimal conditions for coupling FTIR and MS gas analysis systems to the heated furnace outlet. The TG sample carriers are always equipped with a thermocouple for direct measurement of the temperature at the sample. The high capacity of the balance along with constant resolution over the entire weighing range provide the best conditions for using the wide variety of ceramic or metallic sample crucibles and pans in different shapes and sizes. Of course, vacuum-tight construction providing for pure atmospheres goes without saying. The TG 449 F3 Jupiter® is designed for upgrading to simultaneous TG-DSC or simultaneous TGA-DTA. The TGA sample carriers can be exchanged with TGA-DSC or TGA-DTA sample carriers in a matter of seconds so that a very cost-effective upgrade can be made at any time into a full-fledged, universal STA. The TG 449 F3 Jupiter® is one of the versatile TGA systems for routine use in material research and development as well as in quality assurance – primarily in the area of inorganics.
Switch valve for 2 purge gases and 1 protective gas Mass flow control for 3 gas channels (optional) Vacuum-tight assembly up to 10-2 mbar c-DTA® for the calculated DTA-signal, ideal for temperature calibration at TG applications TGA-DSC and TGA-DTA sample carriers for real simultaneous operation Automatic sample changer (ASC) for up to 20 samples and references (option) Coupling with FTIR, MS and GC-MS over a heatable adapter (option) Extension with unique PulseTA® system (option)

|Reactive Gas Exhaust not Escaping|
Hello, we are having an issue where the reactive gas is collecting inside of the instrument and is not exiting out of the instrument from the exhaust port. Ours is set up for use with ammonia and the ammonia doesnt fully exit the instrument causing the balance reading to not read correctly

My question is aboutthe internal balance of the TGA Netzsche 449 F3 Jupiter.
When Ipress "weigh"to tare the balance and then weigh out my sample to analyse, a message appears:
"Cannot weigh using internal balance. Instrument is off"
Please cananyone tell me how toswitch on the instrument (I presume it is the internal balance, not the TGA). Thank you in advance.

|Startup Temperature Problem|
Has anyone had problems getting the correct start temperature for your programs?
I have a Netzsch Jupiter 449 F3 DSC. I have been running experiments in the temperature range 150C to 600C. The DSC never reaches 150C at start-up. It usually starts ~120C and my final temperature is always ~550C.
I have played games such asstarting my program at RT then adding a a ramp step to 150C. The DSC "starts at RT".By this I mean it launches your tempprogrambut itneverreaches 150C before the ramp to 600C happens. I have alsoheated the oven to 150C stopped a program, then started my 150 to 600Cprogram. The 150C drops to about 120 before the ramp to 600C starts. In all cases I get to about 550C max temp.
I realizeI can just add an extra 100 degrees to my measurements but in my past experience DSC's usually start at the temperature you tell them to.
Is this normal? Has anyone else seen this? Am I doing something wrong?
