Thermo Gravimetric Analyzer

Thermo Gravimetric Analyzer

Thermal Gravimetric Analyzer is a instrument that uses thermal weight to detect material temperature-quality changes. The thermal weight method is at a change of the quality of the substance with temperature (or time) under the temperature control temperature.

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 weight 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 (such as the crystalline water in Cuso4 · 5H2O).

Thermal analysis

Thermogram analysis (TG or TGA) refers to a thermal analysis technology that measures the quality and temperature changes of the sample to measure the sample to measure the thermal stability and components of the material under the program control temperature. TGA is more commonly used in R & D and quality control. Thermal analysis is often used with other analysis methods in actual material analysis, comprehensive thermal analysis, comprehensive and accurate analysis of materials

Product Category

Thermal analysis can usually be divided into two categories: dynamic method and static method.

1. Static method: Including the measurement of equivalent quality changes and equal temperature changes. The measurement measurement of equivalent mass changes refers to a method that measures the relationship between the relationship between quality and temperature under the division of the measurement of the measurement material under the division of the constant volatilization. The measurement of equivalent temperature quality changes refers to a method of measuring the relationship between the quality and pressure under constant temperature conditions. This method is accurate, but it takes time.

2. Dynamic method: It is the heat analysis and micro -business heat analysis that we often say. WeChat thermal analysis, also known as DerivativeThermography (DTG), is the first -order guide for TG curves to temperature (or time). The temperature T (or time T) is used to draw the temperature T (or time T) at the material quality change rate (DM/DT), which is the DTG curve
