Industrial Thermogravimetric Analyzer: An Automated and Accurate Solution for Testing Plastic Ash Content

DESCRIPTION / TECHNICAL SPECIFICATIONS

Thermo Gravimetric Analyzer (TGA): Automated and Accurate Plastic Ash Content Testing Solution in Accordance with ISO 3451

In the plastics manufacturing industry and material testing laboratories, precision in determining raw material composition and purity is essential to maintaining strict production quality standards. The Thermo Gravimetric Analyzer (TGA) is an automated thermal analysis instrument engineered to continuously measure the change in sample mass as it is heated within a controlled atmosphere, such as air or nitrogen. This single-instrument system is specifically utilized for fully automatic ash content ($\text{CaCO}_3$) testing of plastics in accordance with ISO 3451 standards.

Core Functions and Operating Principle

The testing process on this Thermo Gravimetric Analyzer is fully automated from start to finish. The sample is heated according to a pre-programmed temperature profile while the system continuously records mass loss caused by organic decomposition until only the inorganic ash ($\text{CaCO}_3$) remains. The resulting measurement data are presented directly as a mass versus temperature or time curve, enabling operators to calculate the ash content directly with high repeatability.

Industrial Applications and Production Efficiency Benefits

While the original ISO 3451 standard outlines a conventional manual furnace method, the Thermo Gravimetric Analyzer (TGA) provides a modern, more accurate, and significantly more efficient alternative for Quality Control (QC) and Research & Development (R&D) laboratories in plastic and polymer manufacturing plants.

Operational and laboratory workflow efficiency is enhanced through the following capabilities:

• Automated One-Key Measurement Operations: The system supports user self-programming procedures to achieve full automation of measurement steps. With dozens of software instructions that users can flexibly combine and save according to their testing protocols, complex operations are simplified into convenient one-key operations.
• Rapid Gas Flow Switching: Equipped with an automated flowmeter that switches seamlessly between two gas flows, delivering fast switching speeds and short stabilization times.
• Convenient Calibration and Maintenance: Standard samples and maps are included as standard accessories to help operators easily calibrate the constant temperature coefficient. Additionally, the detachable sample holder accommodates diverse testing requirements upon replacement and allows convenient cleaning and repair after sample contamination.

Key Technical Features and Advantages

Built to meet rigorous industrial and laboratory standards, this TGA instrument incorporates advanced engineering features:

• High-Precision Weighing System: Utilizes a dish-type balance weighing system operating on the principle of electromagnetic force balance, paired with a high-precision balance offering a sensitivity of one hundred thousandth of a gram ($0.00001\text{ g}$).
• Compact, Safe, and Flexible Furnace Design: Features a compact, one-piece fixed furnace body structure that eliminates the need for vertical lifting or lowering, ensuring safe and convenient operation. The temperature rise and fall rate can be adjusted arbitrarily from $0.1^\circ\text{C}$ to $100^\circ\text{C}$.
• Industrial-Grade Widescreen Touch Display: Incorporates a robust widescreen touch interface displaying comprehensive operational data, including set temperature, sample temperature, oxygen flow, nitrogen flow, differential thermal signal, various switch states, and flow return to zero.
• Reliable Gigabit Ethernet Communication: Features a versatile Gigabit Ethernet cable communication interface that ensures reliable, uninterrupted data transmission and supports a self-recovery connection function.
• Adaptive Multi-OS Software: The software automatically adapts to computer screens of any resolution and adjusts the display mode of each curve according to screen size, supporting both notebooks and desktop computers running WIN7, WIN8, WIN10, WIN11, and other operating systems.
