Preparation of Powdered Coal and Coke SRM Blends

The video tutorial explains the process of creating a sulfur standard with a 1% concentration using coals 2693 and 2692 B. It covers the steps of weighing and equilibrating coal samples, preparing the sulfur crucible, and calculating the final sulfur concentration. The tutorial emphasizes the importance of accurate measurements and moisture determinations to achieve precise sulfur standards.

What is the significance of recording the weight of the sulfur crucible before adding the sample?

How is the total weight of the sulfur sample calculated after adding the components?

What process is followed after moisture determinations to find the exact concentration of the sulfur standard?
