Thermogravimetric Analyzer - TGA Thermal Analysis Instrument - RT to 1550°C, 0.1 μg Resolution

The Master Science Thermogravimetric Analyzer records how the mass of a sample changes as it is heated, held or cooled under a controlled atmosphere. This version works from room temperature up to 1550°C with heating rates from 0.1 to 100°C/min.

A micro-thermal balance with 0.1 μg resolution sits apart from the heat and vibration sources, and the Master Science Thermogravimetric Analyzer is run either from its 7-inch touch screen or from a computer over USB.

Key Benefits

• High temperature reach:: the Master Science Thermogravimetric Analyzer runs up to 1550°C.
• Fine mass detection:: 0.1 μg balance resolution.
• Flexible methods:: five-section programs of ramps and holds.
• Controlled atmosphere:: built-in flow meter with two-way gas switching.
• Fast turnaround:: air cooling shortens the wait between runs.

To record heat flow and mass change in one run, see the Master Science synchronous thermal analyzer.

Product Features

Structure

• Furnace heating element of nickel-chromium wire in double-row winding, reducing interference and improving high-temperature resistance
• Alloy-wire tray sensor resistant to high temperature, oxidation and corrosion
• Power supply and circulation cooling are separated from the main unit to limit heat and vibration reaching the micro-thermal balance
• Top-opening design for easy operation
• Water thermostatic device isolates the chassis and balance from furnace heat
• Furnace body can be replaced to suit requirements

Controller and Software

• ARM processor for fast sampling and processing
• Four-way sampling AD collects the TG signal and temperature signal
• PID heating control with multi-stage heating and constant temperature
• Two-way USB communication allows parameter setting, start and stop from the computer
• 7-inch full-colour 24-bit touch screen; TG calibration can be done on the screen

Applications

The Master Science Thermogravimetric Analyzer supports research and development, process optimisation and quality control for:

• Plastics and rubber
• Coatings
• Pharmaceuticals
• Catalysts
• Inorganic and metal materials
• Composite materials

Common Problems This Analyzer Solves

Thermogravimetric work is easily disturbed; this design tackles the usual causes.

• Furnace heat disturbs the balance:: a water thermostatic device isolates the weighing system.
• Vibration from pumps and power units:: these parts sit outside the main unit.
• Manual gas changes interrupt a run:: the gas path switches automatically in programmed stages.
• Long waits between samples:: air cooling brings the furnace back down quickly.
