Optimized airflow design is beneficial for combined use
• Single step decompression
Heating at 300 ° C (optional 350 ° C) can effectively reduce local "cold spots" on the entire gas transmission pipeline
Heating chamber allows for convenient and precise adjustment of the distance between the quartz glass capillary inlet and QMS
• Flexible design, capable of conducting standard thermal analysis measurements, as well as synchronous measurements with TGA, MS (GC-MS), and MS-FTIR
Durable and easy to maintain, with high sensitivity (able to detect weight loss at µ g level)
TGA-MS can be tested in a humid atmosphere
A hyperbolic four stage rod system with a pre filter can improve the transmission of high mass numbers (large molecules) and also enhance the detection sensitivity of low mass numbers (such as H2, He)
The SEM equipped with separate two emitters and an integrated Faraday cup has a high dynamic range and a long service life
• Can present MS signals and thermal analysis data in three-dimensional form
• Through Proteus®Software for operation and data analysis

A comprehensive heating transmission system and single step pressure reduction design can achieve non condensing gas transmission
The gas transmission system heated to a higher temperature and the design without pressure relief holes can effectively avoid condensation of decomposition products, ensuring high detection sensitivity and facilitating quantitative analysis of identified gases.
The inlet system with capillary tube can also be used for analysis of gases from other sources (non thermal analysis system generated escape gases).

NETZSCH Thermal Analysis Design
NETZSCH thermal analysis equipment has considered the feasibility of combined analysis in the design stage. In the past 40 years, every time a new product is developed, the gas transmission path is considered and optimized: from the furnace outlet, to the adapter and capillary, and then to the QMS inlet. Nowadays, the gas loss caused by condensation is almost completely eliminated, and only a small carrier gas flow rate is needed to completely remove the gas products, minimizing the dilution of volatile products released from the sample, thus ensuring TGA/STA/DL QMS 403 A ë olos®The Quadro combination system has high detection sensitivity.

Silicon crystal organic pollution
The following example uses the comprehensive thermal analyzer STA449F1 Jupiter ® QMS 403 D A ë olos with quadrupole mass spectrometer ® Combined with other methods, trace organic pollutants on silicon chips were identified.
Measure using a large volume sample of 1.6g, place it in an alumina crucible (5ml), and heat it to 800 ° C at a heating rate of 10K/min in a mixed air atmosphere. Due to the release of organic components, the sample exhibited two very small steps of mass loss (0.002% and 0.008%) before 700 ° C. As a demonstration, the following figure only shows the nuclear to mass ratios of m/z 15, 51, and 78.

Lithium Cobalt Oxide Cathode Material - Thermal Stability (QMS)
Lithium cobalt oxide is widely used as a positive electrode material for lithium-ion batteries. The thermal stability of the positive electrode material is also an important factor in designing inherently safer and more efficient battery systems.
In this example, lithium cobalt oxide material that has undergone delithiation is taken out from a button battery and placed in a combination device of NETZSCH STA449F1 Jupiter and QMS 403 Aeolos Quadro for analysis. The positive electrode material exhibits several discrete decomposition steps during the heating process. With the help of mass spectrometry, it is easy to understand the decomposition pathway of materials and the deep structural changes of positive electrode materials after cycling.
