Hello Laura,
Thanks for reaching out to C2C Care! This isn't my area of expertise so I've reached out to some of our experts in order to get more information for you.
In the meantime, for the identification of the chemical causing the odor, contacting a university lab with access to GC-MS would be helpful. Additionally, adding in a sorbent such as activated carbon to the storage solution for the samples could capture some of the off-gassing. As the source of the odor is not yet confirmed, advising staff to wear appropriate PPE when handling is recommended, as well as ensuring the samples are properly labelled as a potential health and safety hazard.
I'll get back to you as soon as possible with information from our experts!
Best Wishes,
Sky
