Research Assistant: ICPMS/Clean Lab 

Stanford University


Responsibilities include the maintenance of clean lab equipment, acid distillation and establishment of a protocol for assessing laboratory lead blanks. As an independent project, I plan to set up and document a routine procedure for the chemical separation of Pb from whole rock powders, including establishing an internal laboratory reference standard.
