LECO instruments offer piece of mind for energy companies validating for quality and compliance by measuring for moisture, ash, volatile content, and loss-on-ignition as well as determination of gross calorific value of various organic fuel materials such as coal.

LECO instruments for thermal gravimetric analysis help observe environmental impact by monitoring composition of arable soils, crops and organic fertilizers.

Available Models

Moisture, Ash, Volatile Content, and Loss-on-Ignition

The TGA801 maintains the core capabilities and reliability of previous generations of LECO macro TGA instruments, while providing key improvements in performance and robustness. State-of-the-art hardware combined with a touch-screen software platform and rugged design provides accurate, high-precision thermogravimetric constituent analysis—moisture, ash, volatile content, and LOI in various organic, inorganic, and synthetic materials. Complying with ASTM standardized methods, the TGA801 is applicable to many industries and applications including coal, cement, catalyst, foods, and feeds.

Macro thermogravimetric analysis (nominal 1 g) replaces the often slow, labor-intensive, traditional manual gravimetric techniques that require multiple sample weighing and transfer steps involving ovens, muffle furnaces, and desiccator equipment. Flexible method settings, automation, and hardware capabilities deliver an automated analysis process while requiring only the manual measurement of the initial sample mass, for maximum productivity in your lab.

Cornerstone Mobile remote software keeps the user updated from their smartphone, tablet, or PC on the instrument’s analysis batch progress, performance, and status while away from the instrument.

Key Features

  • Automated analysis of up to 19 samples for increased throughput.
  • Automatic end point recognition based upon sample mass constancy
  • Stable and precise mass measurements throughout the analysis cycle using an integrated, thermally isolated 0.0001 g low drift balance
  • Precise furnace temperature ramping and set point control provides excellent temperature accuracy with low temperature overshoot
  • Rotating automation sequence provides uniform exposure of all samples to the furnace conditions
  • Automated control of furnace atmosphere and gas flows (air, nitrogen, or oxygen)
  • Flexible method settings enable configuration of system to emulate classic gravimetric test method requirements

Applications

The TGA801 is ideal for the following applications: Coal and Coke, Combustion Residues, Biomass Materials, Catalyst Materials, Soil and Ore Materials, Ceramics, Gypsum and Building Materials, Hydrated Lime and Cement, Flour and Milled Products, Feed Materials, and Resins and Polymers

TGM800 Thermogravimetric Moisture Determinator

The TGM800 provides a high precision, automated solution for moisture determination by replacing the slow, laborous, traditional loss-on-drying technique with an automated primary method. A number of time-saving features have been incorporated into this design, such as the ability to automatically measure up to 16 samples at a time with optional drying time end point recognition, and intuitive touch-screen software with flexible method settings. The TGM800 is applicable to a wide variety of sample matrices including food, feeds, milled products, and agricultural materials, making it a versatile solution for many laboratories.

Key Features

  • Automated loss-on-drying moisture analysis of up to:
    • 16 samples using 1.5 inch diameter aluminum foil crucibles
    • 10 samples using 2.4 inch diameter aluminum foil crucibles
  • Maximized throughput with rapid ramping of the oven temperature and fast cooling post analysis
  • Optimized drying time with automatic end point recognition based upon sample mass constancy
  • Limited sample interaction requirements for reduced operator handling time
  • Integrated 10.1 inch (diagonal) color LCD touch-screen with Cornerstone® software reduces instrument footprint, and promotes an ergonomic and efficient workflow

Gross Calorific Content

Ideal for the measurement of calorific content in solid and liquid fuels, LECO’s AC600 semi-automatic isoperibol calorimeter sets the standard for future calorimetry instruments. Its semi-automated operation, combined with the use of thermodynamic TruSpeed®, obtains a rapid analysis of calorific content and increased instrument throughput without sacrificing accuracy or instrument precision. A new, ergonomically-designed, lightweight combustion vessel assures ease of operation while greatly reducing operator strain.

Key Features

  • Enhanced automation for added productivity
  • Analysis in as little as 5-minute analysis without compromising accuracy or precision
  • Ergonomically-designed vessel promotes easy vessel handling, while enhancing the heat transfer rate
  • Integrated vessel charging station and depressurization ports equipped with quick-release handles speed vessel charging and depressurization process.
  • Intuitive software provides virtually unlimited storage space, simplified data handling, and compatibility with various Laboratory Information Management Systems (LIMS) 

Gross Calorific Content

The AC500 determines calorific value, a key indicator of quality and value in solid and liquid fuels, through measurement of the heat released after combustion of a sample. This stand-alone benchtop unit uses a fully-integrated circulation system for a compact footprint—no additional heaters or coolers required. An integral water-measuring station simplifies sample preparation, and the operating system uses an electronic thermometer accurate to 0.0001°C to measure temperature every six seconds. Two-channel correction is possible through constant temperature monitoring in both the outer jacket and the calorimeter proper.

Key Features

  • High precision across a wide range of sample sizes and ambient conditions
  • Fuse wire or string-ignition combustion vessel
  • Several analysis modes available: Regnault-Pfaundler, Precision, and Predictive
  • An optional string-ignition combustion vessel provides a seamless analysis without wire connections.

Coal and Coke Ash Fusibility Determinator

Our AF700 Ash Fusion Determinator increases your laboratory throughput by automatically determining the ash fusibility temperatures (IT, ST, HT, and FT). The state-of-the-art AF700 features improved operational controls, digital archiving ability, integrated safety features, and increased instrument robustness. 

Key Features

  • A stable, permanently mounted integrated camera is isolated from the high-temperature area
  • An integrated viewing system consistently aligns mirrors with camera and furnace
  • A complete image history for all analyzed samples can be digitally archived and retrieved to make objective determinations and confirmations of deformation temperatures
  • Door interlocks and an integrated carbon monoxide detector provide increased laboratory safety
  • A LED light ring enables low-temperature deformation point measurement
  • High-endurance six-element heating furnace provides durability and long-life
