Samples are to be submitted in screw cap vials with teflon septa to avoid any contamination.
For solids the amount needed for EI or CI experiments is usually less than a ug. For ESI and some special experiments, please consult with the mass spec personnel. High resolution experiments will be performed more effectively if the corresponding low resolution spectrum is first obtained. It is highly recommended to submit a copy of the low resolution data and specify which ions are of interest. This will tell us which peaks manual peak matching is to be performed.
