Chemical Analysis Testing

The activities of the Chemical Analysis Group range from routine testing services to research. Some specific areas of experience include machine deposit, evaporator scale and product contaminant chemical characterization; wood, pulping liquor, pulp and paper chemical analysis; product defect analysis; and methods development. To support this variety of analytical service projects the group employs numerous instrumental analysis techniques including gas and liquid chromatography, mass spectrometry, infrared spectroscopy, emission spectroscopy and capillary electrophoresis. Classical wet chemistry techniques including titrimetry, gravimetry and calorimetry are also used routinely.

How to Request Testing

  1. Send e-mail to with details regarding the nature of the request, the tests required and the problem or issue that is to be resolved. Provide billing contact name and address.
  2. Samples via courier (UPS, FedEx, DHL, etc.) may be sent to the attention of:
    Rallming Yang
    RBI at Georgia Tech
    500 10th St. NW
    Atlanta, GA. 30318-5794

    If sending by U.S., mail replace the ZIP code with 30332-0620

  3. A Purchase Order for an amount to cover the costs for the requested testing is required.
    Georgia Institute of Technology
    Bursar’s Office/A/C Receivable
    225 North Avenue, NW
    Lyman Hall, Suite #111
    Atlanta, GA 30332-0257
    A copy of the Purchase Order sent via fax to 404-894-4778 is requested. 
  4. The sender should have the name of the appropriate RBI contact and phone number on their invoices/P.Os
  5. Receipt of samples coupled with e-mail detailing testing requirements and any background information initiates the generation of an internal project and officially starts the project.
  6. The work request is queued with others in order of time of receipt of samples.  Work requests may be expedited under special circumstances.
  7. A report will be issued within the agreed turnaround time.
  8. Bills are sent separately by mail through the GT accounting system.
