Here are previous samples from Liz's work. I was given these samples to finish out the column chemistry that Liz had started. From previous cave samples, Liz had run through a portion of the cleaning and extracting phase, and I was asked to finish the extraction and isolation phases.
This photo shows an additional cleaning stage which was necessary to prepare the containers for the sample. Containers are labeled to ensure the samples are only transferred between the same two containers.
