Thermal analysis instrument Thermogravimetric analyzer (TGA)

Introduction

Thermogravimetry (TGA) is a technique that measures the change in weight of a sample as it is heated, cooled or held at constant temperature. Its main use is to characterize materials with regard to their composition. Application areas include plastics, elastomers and thermosets, mineral compounds and ceramics as well as a wide range of analyses in the chemical and pharmaceutical industries.

TYPICAL APPLICATIONS

•Quality change
•Thermal stability
•Oxidation/reduction
•Decomposition behavior
•Study on corrosivity
•Component analysis
•Gas adsorption
•Free water and crystalline wcontent

Features

Top Automatic Loading Structure-Stability of Balance System
*The top loading system, vertical structure, easy to operate, not easy to damage, to prevent sample contamination.
*The heating furnace body can be lifted automatically with high control accuracy and easy operation.
*The balance adopts photoelectric structure with high stability and low drift.

Vacuum Sealing Design-Optimizing the Experimental Atmosphere
*The vacuum pump is connected with the instrument for vacuum extraction. Its vacuum degree can reach 10-2 pa, and then can be filled in any setting atmosphere.
 

High Precision Gas Controller
*Users can control the test atmosphere through the rotor f lowmeter (two-way purge gas,
one-way protective gas), and can choose mass f lowmeter to control the purge gas more effectively, provide the most suitable atmosphere for sample testing, and customize corrosive gas according to user’s needs.
 

Excellent scalability
*It can be used in conjunction with infrared analyzer (FTIR), mass spectrometer (MS) and gas chromatography(GC)
