We have an opening for a Post College Appointee to perform sample preparation for trace element analysis by both quadrupole inductively coupled plasma mass spectrometry (Q-ICP-MS) and sector field inductively coupled plasma mass spectrometry (SF-ICP-MS); as well as perform separations and purifications of uranium and plutonium from environmental samples. The isotopic compositions of the purified elements will be determined by multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS). This position is in the Chemical and Isotopic Signatures group of the Nuclear and Chemical Sciences Division.
Perform sample preparation of many types of sample matrices for trace element analysis by Q-ICP-MS and SF-ICP-MS. Sample preparation includes sample digestions and dilutions.
Purify uranium, plutonium and other actinides from environmental matrices using chromatographic separations for isotopic analysis by MC-ICP-MS.
Maintain an accurate and detailed laboratory notebook to ensure results are properly annotated and organized for reports.
Maintain a stock of clean labware necessary to support sample preparation, including re-ordering of general lab supplies.
Manage sample disposal to appropriate waste stream.
Collaborate with group members and the principal investigator on multiple projects.
Perform other duties as assigned.
Recent BA/BS or MS in Chemistry, Geology or a related field.
Experience with sample digestion techniques using thermal methods and concentrated acids.
Experience with selective extraction media and chromatographic separation methods.
Experience with clean room environments.
Proficient verbal and written communication skills necessary to effectively communicate technical information with technicians, peers, and managers.
Interpersonal skills necessary to work in a collaborative research environment and interact with a diverse set of scientists, technicians and other technical and administrative staff.
Experience using personal and/or Macintosh computers to collect, analyze, and document scientific results.
Pre-Employment Drug Test: External applicant(s) selected for this position will be required to pass a post-offer, pre-employment drug test. This includes testing for use of marijuana as Federal Law applies to us as a Federal Contractor.
Security Clearance: None required.
However, if your assignment is longer than 179 days cumulatively within a calendar year, you must go through the Personal Identity Verification process. This process includes completing an online background investigation form and receiving approval of the background check. (This process does not apply to foreign nationals.)
Note: This is a one-year Post College Appointee with the possibility of extension to a maximum of two years. Eligible candidates are recent graduates within two years of the month of their BS or MS degree at the time of the employment offer.
