Note about services, dated March 31, 2020:

Dear Lalonde AMS clients,

This email is an update to our previous note, sent on March 23, indicating the temporary suspension of operations in our sample preparation labs to comply with requirements to reduce the spread of COVID-19.

The University of Ottawa remains open and able to receive sample shipments and packages*. Please notify us prior to shipping any samples and include tracking numbers in your correspondence. Your samples will be securely stored and queued until operations resume.

If you have any questions or concerns, please do not hesitate to contact the sample preparation person with whom  you normally work, or for more general requests, contact us at  


March 23rd:

*A note to clients that are planning on submitting DIC or DOC samples for radiocarbon analysis: Due to the nature of these samples, limited cold storage at our facility and anticipated delays in processing, it is extremely important that you coordinate your shipment with us.

We have updated our recommended sampling procedures to better preserve your samples for longer-term storage. A link to the procedure can be found here. Please contact either Jen Walker ( or Sarah Murseli ( before sampling and submission.
