Automatic Proximate Analyzer (TGA) LPA4000
LPA 4000 provides multi-constituent analysis for up to 19 samples at a time. Typical coal analysis method consists of determination of moisture, volatile matter, and ash content. LPA-4000 with integrated balance combines drying, ashing and weighing processes for improved efficiency, precision, and high sample throughput. The software allows for customization of the analysis steps such as temperature ramping, start temperature & end temperature, programmable gas flows, placement/removal of crucible lids and mass constancy criteria for a fully flexible instrument optimized for every user unique needs.
Key Features
- Integrated with high precision electronic scale. Using thermogravimetry. Quickly, automatically, and continuously tests 19 samples in every experiment. The air-dry basis moisture, ash and volatile constituent can be tested. Automatically tests the Calorific Value, fixed carbon, and hydrogen content of the sample.
- 20-Position Sample Carousal (19 Samples + 1 Reference)
- Adopting the unique integrated configuration of “three temperature grade, double furnace”, the instrument can work in parallel, and hence to reduce the testing time and the constant temperature area in the furnaces do not interfere with each other. So the testing accuracy of air-dry basis moisture, ash, and volatile constituent can be ensured.
- Using the advanced heating element and heat preservation materials to ensure the furnace body in stable condition. Meanwhile, the temperature rise more quickly, temperature control will be more precise, and malfunction rate lower.
- With the advanced and appropriate dust suction and fume exhaust devices, the testing results will be more precise and the laboratory cleaner.
- Data collection, calculation, print, and restoration are automatically done by computer.
- Adopting precise reference source, low temperature drift and high precision operational amplifier, and 12-Bit A/D conversion chip in the controlling card, the instrument has the functions of cold end compensation, over-temperature protection both in hardware and software.
- Adopting the advanced USB technology, one computer can control several instruments. And the synthesized instrument can be composed combined with other instruments.
- Completely support Windows systems; high stability; can link electronic scale and share data in long distance through network.
