Open Access ESI-TOF Fixed

October 29, 2015

Thank you for your patience while the Agilent 6210/6220 ESI-TOF underwent repairs.  There were two problems due to the age of the age of the instrument. 1) COM board that has a hard disk on it failed 2) short in extractor plates/electrodes due to dust accumulation that made it fail tune mode. When voltages were ramped, the whole instrument would shut down and would have to be evacuated again.  After cleaning of the electrodes and removal of what appeared to be metal shavings, the instrument is now acting normally.  We will open it up in SPINAL and you can sign up.

External POs Must Have Correct Address

April 4, 2015

Please note that it is your responsibility as an outside non-Harvard user of the facility to check the PO to make sure the correct organization name: Center for Systems Biology or the Small Molecule Mass Spectrometry Facility is on the Purchase Order. Also, it is absolutely essential to have the correct address on the PO (52 Oxford Street), Cambridge, MA. POs made out to other entities within Harvard or with incorrect addresses are not accepted. Equally as important is to have the correct anticipated amount on the PO.
