2
Weigh a clean, dry ceramic dish and record weight to the nearest 0.1 mg, do not tare balance.
3
Add approximately 5 grams of sample to ceramic dish.
4
Allow sample to cool for 15 minutes, then record stabilized weight of dish and sample.
5
Place sample over gas burner and heat for 10 minutes to ensure all light ends are burned off.
6
Place dish in oven at 900 C for roughly 10 minutes.
7
Using tongs, remove sample and allow to cool in a desiccator for 30 minutes.
8
Reweigh the dish and sample residue after cooled and record weight.
9
Calculate ash by using the formulas below: a. sample and dish – weight of dish = sample weight. b. sample residue and dish – weight of dish = weight of sample residue c. (weight of sample residue / sample weight) * 100 = Ash, mass %.
10
Once finished, rinse dish with toluene, wipe dry and place in desiccator.
