Thermogravimetric Analyzer

Thermogravimetric Analyzer Solutions for Laboratories and Manufacturers

What It Does and How It Works

A thermogravimetric analyzer (TGA) measures changes in sample mass as temperature or time varies. The instrument operates in inert or oxidative atmospheres and records TG/DTG curves. These data reveal thermal stability, decomposition steps and kinetics, oxidation onset, volatile loss, and residue/ash content.

Manufacturing Quality and Technical Advantages

Each system is built in ISO 9001–certified facilities with in-house CNC machining and a dedicated R&D and calibration lab. We are a National High-Tech Enterprise with 20+ utility model patents and contributions to three national standards. Mechanical precision, stable microbalance performance, and controlled furnace profiles support consistent, method-aligned results. One-to-one technical guidance, OEM configuration, and global installation with lifetime support help shorten setup time and reduce risk.

Performance and Specifications

• Temperature range and profiles: From ambient up to 1000–1250°C, with programmable ramps, isothermal holds, and multi-step methods for polymers, elastomers, and inorganics.


• Balance resolution and baseline stability: µg-level resolution with low drift and thermal shielding for clean TG baselines, even during long runs and low-mass tests.


• Atmosphere control: Automated switching between N2, Ar, Air, or O2 with precise purge and flow control for oxidation studies, combustion, and residue determination.


• Sample handling and throughput: Interchangeable crucibles/pans for varied chemistries; optional autosampler and macro-scale setups for routine moisture, volatile, and ash screening.


• Software and data integrity: Method libraries, TG/DTG visualization, kinetic tools, and audit-ready record keeping to support development, QC, and reporting.


• Standards alignment: Predefined methods referencing ISO 11358 and ASTM E1131, supported by factory calibration and traceable reference materials.

Configurations and Options

Choose a standard benchtop analyzer or a high-temperature model up to 1250°C for advanced decomposition and ash studies. Options include corrosion-resistant furnaces, autosamplers, and coupling for evolved gas analysis (TGA-FTIR/MS).

Interfaces for simultaneous measurements (TGA-DSC) are available. OEM customization adapts temperature profiles, materials compatibility, and throughput to specific workflows.

Typical Applications

• Polymers and rubber: thermal stability screening, additive/filler and ash quantification, plasticizer or solvent loss.


• Composites and coatings: resin cure/degradation tracking, inorganic filler measurement, oxidation resistance.


• Chemicals and pharmaceuticals: composition checks, excipient/solvent profiling, degradation pathways.


• Energy and minerals: coal/biomass combustion behavior, carbonate decomposition, moisture/volatiles in ores.

Related Thermal Analysis Instruments

A TGA pairs well with differential scanning calorimetry (DSC) to link transitions and composition with stability. For polymer workflows, combine with melt flow index testers, HDT/Vicat testers, and universal tensile testers to connect structure, processing, and performance from R&D to production.

FAQ

What sample mass range is recommended?

Typical tests use a few milligrams to tens of milligrams, depending on material and sensitivity requirements.

Can I switch between inert and oxidative atmospheres during a run?

Yes. Automated gas switching enables stepwise inert/oxidative programs for oxidation onset and ash determination.

Which methods are commonly referenced?

Workflows often reference ISO 11358 and ASTM E1131. Documentation and reference materials support method alignment.

How do I increase throughput for routine screening?

Use an autosampler and predefined methods for moisture, volatile, and ash tests. Macro crucibles can help when sample heterogeneity is a concern.
