The solution remaining in the AGI after the challenge was approximately 6-10 mL in volume. The AGI solution was given to IVINS, who conducted the post-challenge plating. About 1/10 mL was needed for post-challenge plating, and the remaining volume from the AGI could have stayed in room 115 for weeks afterward, though it usually did not stay there that long. The only samples of Ba remaining after a challenge were contained in the AGI and the plates that were created post-challenge.
