DLS: Brookhaven Instrument Nanobrook Omni ()


Dynamic Light Scattering (also known as Photon Correlation Spectroscopy or Quasi-Elastic Light Scattering) is a technique to determine the size distribution profile of small particles in suspension or polymers in solution. It can also be used to probe the behavior of complex fluids such as concentrated polymer solutions. The NanoBrook Omni particle size and zeta potential analyzer enables fast, routine, sub-micron measurements of size and zeta potential. The instrument also includes Phase Analysis Light Scattering (PALS) measurements for samples with low mobilities.

Steps to become a tool user

  1. Become a member of SNSF.
    Become a member of SMF.
  1. Send Dr. Jeffrey Tok an e-mail to request to be a SMF member
  2. Please complete the mandatory web-based checklist. Please check all the necessary boxes and upload all needed safety forms.
  3. Please attend the next mandatory SMF orientation before attending any equipment training in SMF. Links to all equipment training schedules (note that the safety orientation is on the top entry). The SMF orientation is offered every two weeks.
  4. Self-register yourself to SMF mailing list such that you can be informed on the various important happenings in SMF. Also register for the individual equipment mailing list that you intend to access. Updates on each equipment will be disseminated only through the equipment’s mailing list. The link to sign-up for the equipment list is listed in each of the equipment’s website.
