Electro-spray Ionization Mass Spectrometer |
Object Name |
Spectrometer, Mass |
Object ID |
2005.141.001 |
Description |
Large rectangular coated metal frame; all the sides and front are open showing the internal components except for the right front side which has control units installed; two large blue vacuum pumps are visible on the left side; the top of the instrument is solid and has the sprayer installed on it; the sprayer is a cross shaped round tube made from stainless steel (?), a rack system is attached to the right side of the sprayer. Electrospray Ionization is a technique used, mostly in Mass Spectrometry, to create ions. ESI allows macromolecules, large molecules that are usually biologics or polymers, to be broken down into smaller molecules that are easier to analyze. |

Provenance |
Dr. John Fenn shared the Nobel Prize in Chemistry in 2002 with Koichi Tanaka "for their development of soft desorption ionization methods for mass spectrometric analyses of biological macromolecules". ESI is a technique used in Mass Spectroscopy in which large biological molecules (Macromolecules) are ionized. The instrument was built by Dr. Fenn and his graduate students at Yale University. |
