To Whom it May Concern:
My name is Terik Daly. I am an advanced research student at Oak Grove High School in San Jose California. My current research project involves determining whether or not granatics, the most common rocks in continental crust, go through the depletion of volatile, siderophile, refractory-lithophile, and ferromagnesium elements occurs at a measurable, predictable rate when undergoing S6 shock metamorphism. To do this, I will need to establish a baseline value for each element in the granatic specimens. I have the specimens, but to establish this baseline value, I require the use of a glow discharge mass spectrometer. I have checked with the Menlo Park office of the USGS, but they do not have a GDMS machine. If you have any information regarding the whereabbouts of a GDMS machine, please inform me so that I can contact those responsible for it, to discuss possible use of the machine.
