NEVER remove samples from the autosamplers if they are in the queue (pink in the diagram). Be very careful about the number of the position you remove! If you do remove a sample that is yellow or green in the diagram, note down the number and put it in the same spot in the rack. If there is no space, move one of the samples already in the rack to a position in the front where there is no number.
NEVER allow anyone who has not been trained to be in the NMR room on their own. This is for safety and because I want to be sure that I know what is being told to new users. Training is free and usually scheduled within a week of when it is requested. Training can be requested at http://nmr.chem.mcgill.ca/training – please direct new members to this site.
