The LECO TGA801 builds on the proven performance of previous generations of LECO macro TGA instruments, delivering enhanced robustness, precision, and operational reliability. Combining state-of-the-art hardware with an intuitive touch-screen software platform and rugged construction, the TGA801 enables accurate, high-precision thermogravimetric constituent analysis.
The instrument supports determination of moisture, ash, volatile content, and Loss-on-Ignition (LOI) in a wide range of organic, inorganic, and synthetic materials. Designed in accordance with ASTM standardized methods, the TGA801 is well suited for laboratories serving industries such as coal, cement, catalysts, food, and feed analysis.
Macro thermogravimetric analysis using nominal 1 g sample masses replaces traditional, labor-intensive gravimetric workflows that rely on multiple manual weighing steps, ovens, muffle furnaces, and desiccators. Flexible method configuration, automation, and advanced hardware allow the TGA801 to deliver a fully automated analysis sequence, requiring only the initial manual sample weighing to maximize laboratory productivity.
Cornerstone Mobile remote software extends instrument visibility beyond the laboratory, enabling users to monitor batch progress, instrument status, and performance from a smartphone, tablet, or PC.
LECO TGA801
The TGA801 is ideal for thermogravimetric analysis across a wide range of materials, including:
The TGA801 determines weight loss associated with moisture, volatiles, ash, and Loss-on-Ignition by measuring sample mass as a function of temperature under precisely controlled atmospheric conditions. The multi-sample furnace design enables simultaneous analysis of up to 19 samples.
An analysis begins after samples are logged and empty crucibles are placed into the sample carousel. The system automatically records the mass of each empty crucible before prompting the operator to load samples. Once loaded, initial sample weights are recorded and the selected furnace temperature program is initiated.
The furnace atmosphere is controlled using one of three analytical gases—air, nitrogen, or oxygen—depending on the analytical step. Each method step can be configured with specific temperature set points, ramp rates, atmospheres, and durations defined either by fixed time or mass constancy. Preset method steps for moisture, volatile matter, and ash determination are available and commonly used.
Throughout the analysis, crucibles are automatically indexed and lowered onto the balance pedestal to record sample mass. Mass changes are tracked sequentially for each sample, and results are typically reported as percent mass loss at the end of each step. Additional or alternative calculations can be defined within the method as needed.
An external PC running LECO Cornerstone® software manages all quantitative calculations, stores analytical data, and provides comprehensive reporting and traceability.
