Commissioning Analysis

BEFORE collecting OSL samples, please review the how to sample of our website.

BEFORE commissioning analyses, contact the laboratory (legal@usp.br) to consult on the suitability of the applied methodology to your needs and to pre-schedule the period of analyses. Ideally, contact the laboratory prior to sample collection to inform location and type of sediment, and to consult on sampling and luminescence analysis strategy.

Each sample should contain the following information:

  • Unique sample ID (avoid using OSL-1, OSL-2, LOE-1, LOE-2, etc)
  • Depth below surface (in meters)
  • Latitude and longitude (in decimal degrees)
  • Elevation
  • Estimated age and/or other age control
  • Photos, site descriptions, stratigraphic logs

TURNAROUND TIME

Please reach out to inquire about current processing times for different types and quantities of analyses. Depending on the sample age, luminescence characteristics, and the total number of samples, typical turnaround ranges from 6 to 12 months.
