prepASH¨ 340 Series
Automatic analysis of Moisture, Volatiles, Ash, Fixed Carbon Special application for Coal & Coke as per ASTM no D 7582
prepASH® Series 340 represents the highest level of thermo-gravimetric analysis and offers revolutionary improvement of sample preparation, analysis and documentation.
- Fully automatic thermo-gravimetrical analysis with end-point recognition replaces drying oven, muffle furnace and analytical balance
- 3 Models in prepASH® Series 340 for 12, 19, 29 samples are optimum solution for each application
- Built-in high performance analytical balance 0.0001g
- Selectable atmosphere (N2, O2, Air)
- Easy operation of the instrument from colour touch screen built-in computer (Windows)
- Real-time evaluation of weight loss during the drying and ashing process is shown directly on the
prepASH display and via network to external computer
- Various communication ports: Ethernet, 2 USB ports (for PC, Printer, Barcode reader, Keyboard)
- Printout: complete report with Graphics, Tables, Method and Statistics
- Error free protocols and reports.
Analysis of Coal & Coke as per ASTM no D 7582
- Massive reduction in the work-load through the simultaneous evaluation of the Moisture, Volatiles, Ash and Fixed Carbon content of up to 29 samples in one cycle
- Standard Analysis is easily transferred to prepASH® Series 340 and validated
- Optimisation of analysis time up to 70%
- Automatic calculation and documentation of Moisture, Volatiles, Ash and Fixed Carbone values
- Automatic cycle ensures best reproducibility, quality and throughput
- Graphical report of measuring values, either single or in groups, with sample recognition in colour.
Moisture, Volatiles, Ash and Fixed Carbon Method Reference ASTM D 7582
Equipment
Moisture and volatile matters are determined under protection nitrogen atmosphere.
The ashing step is done under oxidizing atmosphere with oxygen. prepASH® must be equipped with the gas flow control unit.
Set “Volatiles”
Free of charge we supply prepASH® with Al2O3 crucibles with covers, steel turn-table and tweezers.
Reference coal and Calibration
Reference material is used to calibrate the methods for the determination of volatile matter content of samples. prepASH® is delivered with a standard method and pre-calibrated with 3 standards. Customers calibration: the reference materials must cover the full range of expected volatile matter contents of the coal and coke samples that will be routinely analyzed.
Analysis Time
2 to 5 hours
Method and Procedure
Standard analysis is easily programmed on the prepASH® Series 340. The user is guided through the needed manual steps as weighing in, cover and uncover the crucibles.
Procedure
- Load crucibles into the furnace carousel and weight all the crucibles automatically.
- Load the samples in the crucibles and weight them.
- Press “Start”. 4. Cover crucibles after drying.
- Uncover crucibles before ashing.
- Automatic printout of report at the end of standalone analysis.
