Quadrupole ion trap mass spectrometry.

Jae C. Schwartz, +1 more
- 01 Jan 1996 - 
TL;DR: The ability of the QITMS to interface to key separations systems such as HPLC and HPCE through the critical ionization techniques of ESI and MALDI, coupled with the high mass range, high mass resolution, high sensitivity, high-efficiency CID, and MS capabilities of this device, will provide an astonishing array of cost-effective capabilities for the qualitative and quantitative analysis of biological macromolecules.

Monopole Spectrometer, a New Electric Field Mass Spectrometer

Ulf Von Zahn
- 01 Jan 1963 - 
TL;DR: The monopole spectrometer as mentioned in this paper uses an electric field between a two-electrode configuration for analyzing ions of different e/m. The properties of the instrument are derived from an approximate equation for the ion motion.

- 01 Jan 1968 - 
TL;DR: In this paper, a mass spectrometer was constructed in which ions were trapped in a three-dimensional, rotationally symmetric, quadrupole field and then periodically drawn out of the trapping field into an electron multiplier.
