Introduction
An automatic thermogravimetric analyzer is an analytical instrument used for the thermogravimetric analysis (TGA), which measures the change of the mass of the sample as a function of the temperature or the time under the controlled atmosphere, and it is used in the materials, the polymer, the chemistry, the pharmaceutical, and the many other applications. The automatic thermogravimetric analyzer consists of a precision balance, a furnace, a temperature control system, a gas control system, and a control and a data analysis system, and it heats the sample at a controlled rate while the mass is measured continuously, providing the thermogravimetric curve, with the automatic operation and the data analysis; the automatic thermogravimetric analyzer provides features such as the various heating rates, the various atmospheres, and the data management, and it is used for the measurement of the thermal stability, for the analysis of the composition, for the measurement of the decomposition, for the determination of the moisture and the volatiles, for the analysis of the polymers, the composites, and the pharmaceuticals, for the research, and for many other applications; the automatic thermogravimetric analyzer is an essential instrument for the thermal analysis. Automatic thermogravimetric analyzers are used in the materials laboratories, in the polymer industry, in the chemistry laboratories, in the pharmaceutical industry, and for many other applications. With their automatic operation, automatic thermogravimetric analyzers are essential for the thermal analysis.

FAQ
Q1: What testing scenarios is this analyzer mainly applied to?
A: The automatic thermogravimetric analyzer is used in materials science, pharmaceutical development, polymer research, ceramics, metallurgy and quality control laboratories to measure weight changes of materials as a function of temperature under controlled atmosphere. It supports thermal stability evaluation of polymers and plastics, decomposition temperature determination, moisture and volatile content analysis, filler and ash content measurement, oxidation stability testing, compositional analysis of composites, and pharmaceutical polymorph and degradation studies. The high-sensitivity microbalance detects minute weight changes during heating, revealing decomposition temperatures, reaction kinetics and material composition. It is essential for materials research, product development, quality control and failure analysis in polymer, pharmaceutical, ceramic, metal and composite industries, where thermal stability, decomposition behavior and composition are critical for material selection, process optimization, product quality and regulatory compliance.
Q2: What standards does the analyzer comply with?
A: The TGA supports methods referenced in ISO 11358 for polymers thermogravimetry, ASTM E1131 for compositional analysis, ASTM E1868 for loss on drying, and relevant GB/T standards for thermal analysis. The instrument complies with relevant laboratory safety standards. Temperature and weight calibration should use certified reference materials traceable to international standards.
Q3: What is the warranty period for the whole machine and key components?
A: The whole TGA system is covered by a 12-month warranty. The microbalance, furnace, gas control and controller are covered, while sample pans, gas and calibration standards are consumables. Damage from improper sample loading, corrosive samples or unauthorized repair is excluded. Extended service contracts are strongly recommended for this high-value instrument.
Q4: Is this device difficult to operate? Is professional training required?
A: TGA operation requires specialist training in thermal analysis, sample preparation and data interpretation. We provide comprehensive training, operation manuals and application support. Proper sample preparation, gas selection, temperature program setup and result interpretation are essential for quality results.
Q5: What is the typical lead-time for order delivery?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is regular calibration required? What is the recommended calibration cycle?
A: Temperature calibration with certified reference metals recommended every 3-6 months. Weight calibration with certified weights periodically. Balance performance verified before each use. Furnace and gas system maintenance per manufacturer schedule. Full system performance verification annually.
Q7: Are supporting consumables universal?
A: Sample pans, gas and calibration standards are available from specialized suppliers, though compatibility should be verified. Long-term consumable and gas cost is moderate depending on usage intensity.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes temperature range, atmosphere control, sample capacity, autosampler and software modules. Custom orders require detailed application specification and extend lead-time. Users should define sample types, temperature range, atmosphere and required sensitivity before configuration.
Q9: Does the purchase include on-site installation and commissioning service?
A: Yes, TGA systems include on-site installation, commissioning, calibration and comprehensive operator training by certified thermal analysis specialists. Site preparation guidance is provided before delivery to ensure vibration isolation, gas supply, power and environmental requirements are met.
Q10: What types of samples are compatible with this equipment?
A: The TGA analyzes solid and powder samples including polymers, pharmaceuticals, ceramics, metals, composites and minerals within the temperature range and sample capacity. Samples that evolve corrosive or toxic gases require appropriate exhaust handling and may damage the balance or furnace. Very large or bulky samples should be reduced in size. Users should select appropriate sample pan material for the temperature and atmosphere, ensure proper gas flow, calibrate temperature and weight regularly, and follow proper sample preparation to ensure representative, reproducible thermogravimetric results.
