## Abstract High energy gycerol cluster ions from an electrohydrodynamic ion gun have been used as a primary ion beam to generate secondary ions of proteins with molecular weights up to 29 kDa and oligonucleotides. The technique not only demonstrated good performance in the picomole/nanomole range

β¦ Synopsis
Use of a Microchannel Array Detector in a Four-Sector Tandem M a s s Spectrometer Sensitivity and resolution are two important parameters of a tandem mass spectrometer used to obtain structural information on relatively large molecules (presently up to M, -3000) of biological significance. These materials are often isolated in very small quantities, therefore, sensitivity without loss of unit mass resolution is at a premium.

A method is described for carrying out triple mass spectrometry (MS/MS/MS) experiments with an electrically floated collision cell in the third field-free region on a tandem double-focusing mass spectrometer. The method described may use magnet calibration obtained at any accelerating voltage and is
