QA Boot Camp - Summer 2015

Quality Assurance (QA) is a critical component of the FSES Program. We are committed to providing the highest quality analytical service and research support. In keeping with this commitment, we held an internal QA “Boot Camp” in the summer of 2015. The QA Boot Camp included:

  • 6 classroom sessions with instruction and group discussion
  • Mock audits, led by teams of staff and students, of laboratory operations including:
    • Sample receipt, handling, storage
    • Equipment selection, usage, maintenance
    • Data generation, storage, analysis
    • Laboratory safety, organization
    • Facilities size, maintenance, sanitation
    • Standard Operating Procedures creation, implementation, periodic review
    • Personnel training, documentation
    • Archiving samples, data
    • QA Program implementation, inspection, oversight
  • Successful Boot Camp completion by 15 staff and students


After a seems-like-forever remodel, the FSES analytical instrument suite is complete! Our state-of-the-art facility contains two identical Agilent 7890A - 5975C GC-MS systems, an Agilent GC-ECD 6890, a Markes Unity thermal desorption chamber coupled with an Agilent 6890A - 7000 GC-MS and two triple-quadrupole Agilent 7890A - 7000 GC-MS-MS systems. This array of instruments allows us to couple high-throughput analytical chemistry with extraordinary sensitivity, accuracy and precision.

NEW Additions to the Program!

During phase I, we added a new 500 ft2  sample receiving and sample preparation space.  During phase II we added 300 ft2of space for instruments.  We have improved work-flow and site-lines throughout the facility and added a second triple-quadrupole QQQ instrument to the group. We continue to strive to streamline our processes and maximize our analytical capabilities. Stay tuned!

Research Highlight: Silicone Wristband Personal Monitoring Device

Accurately assessing a person’s exposures to putative environmental toxicants is central to the challenge of determining environmental health effects. The lack of low cost, easy-to-use personal sampling technology hinders our ability to understand the effect of the environment on health.

We are developing common wristbands to serve as passive samplers that quantitate chemical exposure from our environment. We have shown these simple wristbands, when appropriately prepared provide a simple solution for studies into chemical exposures. With our powerful and sensitive analytical techniques refined over two decades, over 1200 common environmental contaminants can be analyzed for low cost.

If you would like to know more, please see the full publication and follow the additional research we are pursuing with the wristbands (see more here). You can also contact us for more information or to suggest a collaboration.

We are also developing a program to make wristbands available to the public. For more information, please visit Citizen Science and signup for updates.
