Sample processing at the Mercury Research Lab

These steps describe the events and steps that we follow to receive, process, and deliver data for your samples. Please contact the Lab staff at mercury@usgs.gov with any questions about this process.

 

  1. Sample cooler arrives. Immediately upon receipt at the laboratory, sample containers are checked against the Cooler Inventory form and Request for Analysis forms. The forms are dated and signed by the person responsible for log-in of the samples. A log-in number is assigned to each sample container that relates the bar code to the project and site, date, time, and depth of collection.
  2. Sample information is entered into the database. Used or dirty sampling equipment is rinsed with tap water in the prep room and placed in bins to await cleaning. Samples requiring refrigeration or freezing upon receipt are handled appropriately and in a timely fashion to preserve their integrity.
  3. Samples are processed according to laboratory procedures and analysis type methods. Samples are tracked throughout processing using the bar code on the sample container.
  4. At any time before you receive lab results, if you determine that the site name, station ID, or other information on the Request for Analysis form is incorrect, contact the Lab immediately at mercury@usgs.gov.
