Thermogravimetric Analyzers SPTGA

High-Pressure Water Vapor Thermogravimetric Analyzer

Thermogravimetric analysis under pressurized water vapor atmospheres, breaking the monopoly of imported instruments in this niche.

High-Pressure Water Vapor Thermogravimetric Analyzer

High-Pressure Water Vapor Thermogravimetric Analyzer

The SPTGA measures the relationship between sample mass variation and changes in temperature and pressure under a programmed temperature control mode. It is designed to investigate thermal stability, decomposition characteristics, and decomposition kinetics under ambient pressure, pressurized common atmospheres, and complex atmospheres including water vapor — over a wide working temperature range.

Key Specifications

Atmosphere Ambient / pressurized / water vapor
Temperature Mode Programmed temperature rise
Analysis Type Non-isothermal thermogravimetric
Pressure Vessel Pressure-resistant reaction vessel
Water Vapor Source External water vapor generator

Working Principle

A crucible containing the sample is placed into a pressure-resistant reaction vessel. The reaction vessel pressure is adjusted to the experimental target value, and the reaction atmosphere is introduced. After pressure stabilizes, programmed temperature rise begins. For water vapor tests, a water vapor generator connects to the water vapor inlet. Once reactor pressure reaches the experimental requirement, water vapor is injected according to the needed content, and programmed heating begins.
