Lift-type Thermogravimetric Analyzer      

Product Introduction

Instrument Overview

Thermal gravimetric analysis (TG/TGA) involves monitoring the mass variation of a sample as a function of temperature or time during heating, constant-temperature, or cooling processes; its purpose is to investigate the thermal stability and composition of materials. This technique is widely employed in research and development, process optimization, and quality control across various fields—including plastics, rubber, coatings, pharmaceuticals, catalysts, inorganic materials, metallic materials, and composite materials.

Instrument Purpose

Measure and investigate the following properties of the materials: thermal stability, decomposition behavior, adsorption and desorption, oxidation and reduction, quantitative composition analysis, influence of additives and fillers, moisture and volatiles, reaction kinetics, etc.

main features

1、Equipped with an imported mass weighing balance featuring built-in internal calibration and temperature compensation functions, it responds rapidly to mass changes, ensuring superior accuracy and repeatability;

2、The instrument features a built-in mass level guidance function; within the weighing pan's range, changes in the sample's position do not affect the mass measurement result.

3、The internal balance chamber is equipped with a standalone MFC module, which provides the balance with a stable inert gas protection environment; the flow rate can be automatically configured and adjusted via software;

4、The balance chamber is also equipped with a constant-temperature water bath system, which maintains a stable ambient temperature and significantly enhances weighing stability;

5、The instrument can be used for experiments involving sample weight gain or weight loss, such as the adsorption and decomposition processes of samples;

6、The furnace features a dual-axis lifting and lowering design with an electric vertical lifting function, as well as a horizontal rotation capability.

12、Equipped with an innovative 360° omnidirectional rotation sensor mount, it enables continuous, stepless rotational positioning within the horizontal plane and allows for reliable locking and securing at any angle. Operators can load samples from the most comfortable and convenient angle based on the laboratory bench layout and their personal preferences, significantly enhancing operational efficiency, reducing operational complexity and potential risks, and making cleaning and maintenance more convenient;

13、The sensor mount is constructed from imported materials, offering enhanced resistance to corrosion and oxidation, as well as high sensor sensitivity;

14、Equipped with a standalone multi-level thermal radiation shielding module that maximizes the suppression of thermal radiation and convective heat transfer, thereby ensuring signal stability; this fundamentally and effectively resolves issues such as baseline drift and signal noise caused by thermal disturbances.

15、The sensor signal sampling frequency can be set between 0.05 Hz and 10 Hz, offering greater flexibility in experimental methodology and enhanced data control;

16、The dual-temperature-sensor design allows for simultaneous measurement of both the internal furnace temperature and the sample temperature;

17、The full-temperature control system employs an optimized dynamic PID algorithm, which significantly mitigates the limitations of traditional PID algorithms and enhances the robustness of the dual-mode temperature control system;

18、The device supports two experimental modes – FTC and STC – which allow for more intuitive and flexible temperature control, catering to the diverse experimental requirements across various application scenarios. It enables more precise temperature regulation during the experiment and more efficient analysis of sensor signals, ensuring precise control over experimental outcomes;

19、An optional standalone AI interaction module is available; this module recommends expert-level experimental protocols based on user requirements, making the experimentation process more efficient and reliable, thereby significantly enhancing overall experimental efficiency.

20、The 12-stage programmable temperature control feature enables greater diversity in experimental approaches; the device also features a cyclic scanning function with a maximum scanning count of 9,999 cycles, and automatic data saving is supported.

21、Both the lower-level and upper-level computers of the equipment system feature a multi-point temperature calibration function, catering to the requirements of various experimental scenarios and thereby enhancing the accuracy of temperature measurements;

22、The instrument is equipped with an imported high-frequency core control processor, offering faster computational processing speeds and more efficient control;
