Pheasant Memorial Laboratory

Basic Chemistry lab

The lab has facilities for major-element analysis of geological materials, consisting of high-temperature furnace, precision balance, and chemical fume food. Titration called Wilson’s procedure is applied to determine ferrous iron abundance. Gravimetric method is applied to determine volatile abundance in rocks.
