As geothermal steam containing contaminants such as boron, arsenic, and mercury is passed through a turbine-condenser system, the contaminants preferentially collect in the initial condensate produced from the steam. The organometallic compounds are useful in semiconductor applications as chemical vapor or atomic layer deposition precursors for film depositions. A cut section for an optical-path is provided in the second interconnection board. A laser with adequate vitrification power will then vitrify, or change to glass, the surface of clay-containing objects including the colorant carrier falling in the path of the laser beam. The invention may further include the capability to match an orientation of a biopsy probe which has been rotated upon procurement of a biopsy sample.
