• Simultaneous TG/DTA improves ease of operation, sensitivity and analytical accuracy of conventional stand-alone systems.
• If flexibility and high performance is needed in various applications, the new DTG-60/60H combines them all: Basic functions required by simultaneous thermogravimetry/differential thermal analysis (TG/DTA) measurements are improved. Atmosphere control is programmable. As in DSC, the TA-60WS provides advanced acquisition, analysis and report functions which ensure comfortable simultaneous measurements.
• The DTG-60A is a new automatic DTG which defines new standards in autosampler technology. The built-in automatic sampler can easily be operated and programmed, compared to the complicated operation and setup of conventional autosamplers.
• Up to 24 samples can be set up for analysis and additional sample trays can be used to quickly reload the autosampler, providing more than 24 hours of fully automatic analysis at one time.

High-accuracy Roberval mechanism top-loading balance system

The Roberval mechanism has been adopted, so that the sensitivity does not change due to changes in the center of gravity of the sample caused by melting, etc.

What is the Roberval mechanism?

Regardless of where the sample is placed in the detector pan, the sensitivity of the balance remains constant. The sensitivity does not change due to changes in the center of gravity of the sample caused by melting or expansion due to heating.









 

With a simple balance, the measurement varies depending on the position in which the sample is placed. There is a possibility that the result will change every measurement, so the reproducibility is low. When the beam is heated in the furnace the distance between the fulcrum and the sample changes due to thermal expansion, so the measurement changes. If the center of gravity of the sample varies during measurement due to melting or expansion caused by heating, then the measurement will change.

On the other hand, the Roberval balance has a parallelogram frame structure with freely moving sides, as shown in Fig. B. If pans are placed on its vertical beams and the sample and weight are placed on top of these pans, they will be balanced regardless of where the sample and weight are placed if their masses are the same. The sample may be placed anywhere on the pan.

Flow channels for reaction gas provided

With TG/DTA measurement, qualitative and quantitative analysis, the study of reaction mechanisms, and evaluation of thermal resistance can be carried out by observation of various types of reactions and interactions between the sample and special atmosphere gases. With the DTG-60 Series, various applications are supported by configuring individual flow channels. There is one gas inlet, so the gas can be led directly to the sample, and time is not required for the reaction.
