Sulfur (³⁴S) Tips

Shipping
Please read and follow the instructions carefully to ensure safe transit and appropriate handling of your samples.

1) Please complete the online Analysis Order Form and Sample List for your samples and email these forms to sif@ucdavis.edu. Please include a printed copy of these forms with your samples. The SIF uses this form to track your samples and to contact you regarding receipt of samples, data, and invoicing. For mixed analysis requests, we require the completion of a separate form for each type of analysis.

Also, please include:

-A specific description of each sample, including freshwater vs. seawater species and approximate elemental composition.

-The expected range of isotopic composition of enriched material.

The sample list should include weights where appropriate. If more rows are required in the sample list, simply add the rows and continue the numbering in column A.

2) If you are shipping soils from outside the USA, please contact us to receive a copy of our Soil Import Permit to include with your shipment.

3) Carefully package the sample trays to protect them during shipping. Single trays should be wrapped with multiple layers of bubble wrap and can be shipped in a padded envelope or box. Multiple trays should be banded or taped together and shipped in rigid box filled with packing material. Desiccants, such as Drierite, should not be included with samples unless contained within a spill-proof, separate package.

Failure to properly package and protect trays often results in sample loss during shipping.
