Lab Vacuum Thermal Gravimetric Analyzer 

Product description:

A. It is a instrument that uses thermal weight to detect the temperature-quality change relationship.

B. At the process temperature, the quality of the substance is mainly measured with the continuous change of temperature and time.

C. When the measured substances are sublimated, vaporized, decomposed by gas, or losing crystalline water during the heating process, the quality of the measured substances changes.

D. At this time, the thermal curve was not a straight line but a decline.

E. By analyzing the thermal curve, you can know how much the measured material is changed, and according to the loss of weight, how much material can be calculated.

Product overview

Vacuum heat loss analyzer, English Vacuum thermal Gravimetric Analyzer, abbreviated as VTG. It is a instrument that uses thermal weight to detect the temperature-quality change relationship under high vacuum conditions. At the process temperature, the quality of the substance is mainly measured with the continuous change of temperature, time, and vacuum.

When the measured substances are sublimated, vaporized, decomposed by gas, or losing crystalline water during the heating process, the quality of the measured substances changes. At this time, the thermal curve was not a straight line but a decline. By analyzing the thermal curve, you can know how much the measured material is changed, and according to the loss of weight, how much material can be calculated.

If you use it with the online mass spectrometry, you can also accurately know the composition and structure of the lost material.

The existing ordinary thermal analyzer is usually carried out in a certain gas atmosphere, such as high -purity nitrogen or high -purity oxygen environment. The existence of the gas atmosphere will affect the diffusion of substances and affect mechanical analysis and research. It may also work with material to introduce other influencing factors.

When the heat analysis of high vacuum environment conditions that need to be studied across the gaseous atmosphere, vacuum thermal analysis is needed.

Studies have shown that many substances show obvious differences in the height of thermal atmosphere even in a vacuum environment. The study of this difference helps to further understand the thermal performance of the material and obtain more valuable data.

The BSD-VTG vacuum heating analyzer is a research-level analysis instrument. It is equipped with a molecular pump high vacuum acquisition equipment, which can perform thermal analysis under high vacuum conditions. It can be used with online mass spectrometry to form a VTG-MASS combination, which is the top means for vacuum thermal analysis.
