Charges: $50/hour, External users $150/hour ($75/hr trained running own sample) - 3 hour cap

(Future charges subject to change)

This instrument varies the sample temperature in accordance with a program and simultaneously measures the change in mass of the sample (TG) and the temperature difference between the sample and a standard substance (DTA). An analytical balance mechanism (Roberval mechanism) offers high reproducibility and allows worry-free operation even for measuring sample weights. Two models are available for different maximum measurement temperature requirements-the DTG-60 (max. 1,100 °C) and the DTG-60H (max. 1,500 °C). Corresponding DTG-60A and DTG-60AH models with a built-in autosampler are also available to automatically measure up to 24 samples.

The Shimadzu DTG-60H is a high-performance simultaneous thermogravimetric/differential thermal analyzer (TG/DTA) designed for high-temperature material characterization. 

Sample Types:

• The instrument is highly versatile, accommodating a wide range of materials and states: 

• Solid Materials: Ceramics, glass, metals, minerals, and carbon black.

• Polymers & Rubbers: Plastics and synthetic rubbers (e.g., SBR) for stability and composition analysis.

• Chemicals: Agrochemicals, synthesized chemicals, and organic salts like calcium oxalate.

• Fuels: Biomass and biofuels for combustion property studies.

• Atmosphere-Sensitive Samples: Reactions with special atmosphere gases (oxidizing or inert) can be studied using the integrated flow channels. 

Core Capabilities:

• Simultaneous TG/DTA: Measures mass change (TG) and heat flow differences (DTA) concurrently in a single furnace, ensuring identical conditions for both data sets.

• High Temperature Range: Operates from ambient to 1,500°C, distinguishing it from the standard DTG-60 (1,100°C).

• Precision Balancing: Features a unique Roberval mechanism and X-shaped fulcrum that prevent sensitivity changes due to thermal expansion or vibration, ensuring high accuracy even for trace samples.

• Broad Measurement Range: Supports a measurable mass change of ±500 mg with a maximum sample weight of 1g and DTA range of ±1,000 µV.

• Advanced Atmosphere Control: Includes programmable gas flow channels that allow reactive gases to be led directly to the sample while inert gas purges the balance.

• Connectivity: Can be interfaced with IR spectroscopy or mass spectrometry (TG-FTIR/TG-MS) to analyze evolved gases.

• Efficiency: A low-mass furnace and built-in cooling fan facilitate rapid cooling between runs, increasing daily sample throughput.
