The Plasma Chemistry Laboratory at CAIS is an analytical geochemistry laboratory specializing in the analysis of trace elements and isotope ratios in biological, environmental, geological, archaeological and other materials.

The laboratory is equipped with three Thermo X-Series II ICP-MS and an Agilent HPLC-ICP-MS for the analysis of heavy metals and minor, trace, and rare earth elements. Mercury is done using the Milestone DMA-80. We have a wet-chemistry lab fitted with a digestion block, a Milestone Ethos microwave, and supplied with ultra-pure water. We also have access to a class 100/1000 Cleanroom for processing sensitive samples, upon request. Please note that we do not use HF in our digestion procedures and therefore for soils and silicates we offer a leach analysis rather than a total digestion. For further information, please see our Resources or contact us.

Sample Submission Guidelines

If you are a first-time client (or a repeat client requesting a different service) please contact us before sending your samples so we can help you choose the right analysis for your samples. If you are a returning client please give us a heads-up when you’re sending samples.

1. For water samples, or if you plan to do the digestions yourself please refer to our Sample Preparation Guidelines for information on preparing the samples.

2. Label tubes clearly with a unique identifier. Close the lids tightly and seal well with parafilm. For liquids, cell pellets, or animal tissue, seal the tubes in a plastic bag with some paper towel or an absorbent pad in case of leaks (for fizzy liquids or alcohol please double-bag, with absorbent in the second bag as well). Package in a crush-proof box or container. Proteins, cell pellets, and animal tissue should be shipped frozen in an insulated box with dry ice.

3. Complete the Plasma Chemistry Laboratory Sample Submission Form, and include a printed copy in the shipment (outside of the bag for animal, cell pellet, or liquid samples). For cell pellets and animal tissue please record the sample weights on the sample submission form. If you are sending more than 10 samples, please also e-mail us an electronic copy of the sample submission form or a sample inventory.

4. Address the package to:

Attn: Plasma Chem Lab
Center for Applied Isotope Studies
120 Riverbend Rd.
Athens, GA 30602
USA

Please note we do not receive samples on weekends or holidays so please DO NOT select any Saturday or weekend delivery options. For frozen samples, please try to time your shipment so the samples do not spend the weekend on a truck or in a warehouse (i.e., ship them on a Monday or Tuesday so they arrive on a Wednesday or Thursday).

5. Local clients may drop off samples with a completed sample submission form Monday – Friday (excluding UGA holidays) 8:30am – 4:30pm.

 

Analytical Fees & Turnaround Times

We would like to continue to provide you the excellent service to which you have become accustomed. Economic shortfalls, increased overhead, and supply chain disruptions are affecting us all, and our rates have not yet caught up with costs. We will be revising our rates in late summer/early fall 2022 and will announce the new rates well in advance. In the meantime, the Center is reallocating resources, which will result in slower turnaround times for the Plasma Chemistry Laboratory. Rather than risk a decrease in data quality, we have made the difficult decision to reinstate our minimum order charge and adjust our turnaround times accordingly. Standard turnaround time is now 2 – 8 weeks.

For all external (non-UGA) samples received after May 15, 2022: the minimum charge per invoice is $200, and we are suspending all Rush (expedited) service.

For all UGA samples please contact us directly to inquire about small sample sets and Rush (expedited) service.

If you require a formal quote, we would be happy to provide one if you let us know the sample type, number of samples, type of analysis and sample preparation required, turnaround time, and what elements you need. For training, demos, or large/ongoing projects please contact us. We accept payment by check, credit card, purchase order, or bank wire. UGA clients may also pay using their SpeedType. If you plan to pay by wire, please let us know in advance. A $25 wire fee will be added to your quote and invoice. If you plan to pay by purchase order (PO) and you work at a university or large company you will most likely need a formal quote before you can request a PO, which should be done before submitting samples. Please send us a copy of your PO.
