The Eastern Analytical Symposium (EAS) and Exposition is an American organization that sponsors a Symposium and Exposition generally held in Princeton, New Jersey, every November. The Symposium is attended by over 2000 scientists and typically contains several hundred papers by the world's leading authorities on analytical chemistry.
The associated exposition contains information on technology and information from companies that provide instrumentation and services for the community of analytical scientists.  In addition, the EAS provides an ongoing education program that includes technical short courses and professional development workshops for laboratory scientists, as well as general-interest sessions directed at the public, especially students and their chemistry teachers.
