Speakers should arrive in their presentation rooms at least 30 minutes before their scheduled speaking time. Poster presenters should set up their poster at least 30 minutes before the start of their poster session.

Poster Session Guidelines

All materials must be confined to:

  • 4-foot-high by 8-foot-wide display board in the convention center
  • 4-foot-high by 6-foot-wide display board in hotels

Authors must mount their poster during the one hour before the scheduled session start. Poster numbers supplied by ACS will be in the upper corner of each poster board, and this number corresponds with the number assigned to each poster in the technical program. Pushpins will be available at the poster session. Authors must remain with their posters for the duration of their scheduled session as indicated in the technical program. All posters must remain up until the session ends and then must be removed within one hour. ACS cannot assume responsibility for materials beyond these time limits.

Sci-Mix presenters may begin poster setup at 7:15 PM (45 minutes before the session begins). Each presenter may be accompanied by one assistant only, and both people are required to check in before entering the hall. After exiting, presenters will not be permitted to re-enter the hall until the session begins at 8:00 PM.

Technical Session Equipment

Each technical session meeting room will be equipped with the following:

  • LCD projector
  • screen (wide screens)
  • lighted podium
  • podium microphone or lapel microphone
  • laser pointer

Speakers need to provide their own laptops or arrange for specialty equipment directly with their symposium organizer and/or division program chair. To request other specialty equipment (at the standard fee), contact an ACS Operations Office during the meeting.


Speaker Ready Rooms

Ensure compatibility with LCD projectors, fulfill last-minute audiovisual equipment orders or rehearse your presentation. Visit an ACS Operations office for room locations and hours of operation.


Withdrawal Notices

Send an e-mail to and contact your symposium organizer immediately.
