Moisture, Volatiles, Ash and Fixed Carbon
Analysis of Coal & Coke as per ASTM D 5142-09
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. Included in the supply are 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 and content of samples. prepASH® is delivered with a standard method and pre-calibrated with 3 standards. Customer the 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
Standard analysis is easily programmed on the prepASH® Series 340. The user is guided through the manual steps such as weighing in, covering and uncovering the crucibles.
Load crucibles into the furnace carousel and weight all the crucibles automatically.
Load the samples in the crucibles and weigh them.
Cover crucibles after drying.
Uncover crucibles before ashing.
Automatic printout of report at the end of analysis.
Note: Paid installation is required and not included in pricing. Standard installation is 2 days, budgetary estimate $4,500 (Contiguous US,
most Canadian locations).
Extra days required by failure to meet site-prepared condition will be an additional billing of $1,000 per day.
Installation charges are not subject to dealer discount.

Measuring Weight Loss Through Automated Ashing with a Thermogravimetric Analyzer (TGA)
Fully automatic thermo-gravimetrical analysis with end-point recognition replaces drying oven, muffle furnace and analytical balance
3 Models in the prepASH® Series 340 with 12, 19, or 29 samples are the optimum solution for various applications
