Sylab's TGA 1500 is an automated instrument that determines moisture content, ash content, volatile matter content, loss on ignition (LOI), and fixed carbon content in a wide range of organic, inorganic and synthetics. Thermogravimetric analysis replaces traditional analytical techniques that are slow, laborious and involve multiple steps with multiple laboratory equipment such as muffle furnaces, ovens and balances. The TGA 1500 with integrated scale combines the processes of drying, incineration and weighing. This improves efficiency, precision and enables high sample throughput. The TGA 1500 is usable in various industries and applications including coal, coke, ores, cement, lime, food, feed and many others.
The 19-position carousel allows for high sample throughput. Two TGA 1500s can be controlled from a single PC, increasing productivity and reducing costs.
Once the analysis is complete, the cooling process automatically starts with the user-programmable opening of the furnace lid to improve cooling time.
The pneumatic carousel control mechanism increases long-term reliability by eliminating oscillation and increasing position accuracy. Automatic control of the furnace atmosphere and programmable gas flow rates (air, nitrogen or oxygen).
High-power heating elements provide rapid temperature rise and excellent stability. The integrated multi-element design ensures that temperatures are uniform throughout the furnace chamber.
Single carousel for holding crucibles with manual handling of crucible covers, automatic end point recognition, user programmable method parameters as well as skipping of empty crucibles to optimize analysis time.

In the TGA 1500 thermogravimetric analyzer, the mass of samples in a controlled atmosphere is repeatedly recorded as a function of temperature or time or both. In the TGA 1500 thermogravimetric analyzer, the sample size is approximately 1 gram (or up to 5 grams). All mass measurements are performed by the system. In a typical analysis, the temperature is normally raised from room temperature to a specific temperature and maintained at that temperature for a prescribed time. The change in mass is recorded repeatedly throughout the procedure. Thermogravimetric analysis of the sample is completed when the sample reaches a constant mass as defined in the instrumental operating parameters. Alternatively, the measurement can be considered complete after heating the sample for a specified period of time.
The TGA 1500 consists of a computer and a multi-sample furnace which allows up to 19 samples to be analyzed simultaneously.
A suitable analysis/test method can be selected from the software. After selecting the test method, the empty crucibles are loaded into the furnace carousel. The analysis method controls the movement of the carousel, the furnace and the balance operation. Upon completion of crucible tare, each crucible is presented to the operator for sample loading. The initial weight of the sample is measured and saved automatically. Once all crucibles are loaded, the analysis begins. Following a moisture analysis, the furnace lid is opened for the volatile matter. After the crucible covers are placed on, the analysis of the volatile matter will begin, and the covers will be manually removed after the analysis is finished. The weight loss of each sample is monitored and the furnace temperature is controlled according to the chosen analysis method. The percentage weight loss for each sample is reported at the end of each analysis step.
