Apr 27, 2022

Appl. No.:

17/730830

Inventors:

- West Lafayette IN, US
Dalton Snyder - West Lafayette IN, US
Christopher Pulliam - West Lafayette IN, US

International Classification:

H01J 49/00
H01J 49/42

Abstract:

The invention generally relates to systems and methods for precursor and neutral loss scan in an ion trap. In certain aspects, the invention provides a system that includes a mass spectrometer having an ion trap, and a central processing unit (CPU). The CPU includes storage coupled to the CPU for storing instructions that when executed by the CPU cause the system to excite a precursor ion and eject a product ion in the single ion trap.

International Classification:

H01J 49/00
H01J 49/16
H01J 49/04
G01N 33/68

Abstract:

The invention generally relates to systems and methods for on-line reaction monitoring. In certain embodiments, the invention provides systems that include a reaction vessel having an outlet, a quantitation unit coupled to the outlet and configured to introduce internal standard and solvent into reaction solution flowed from the reaction vessel, one or more ion generating devices that receive flow from the quantitation unit, and a mass spectrometer. In certain embodiments, the invention provides systems for multiple reaction monitoring that include a plurality of reaction vessels, a plurality of ion generating devices, a plurality of channels, each channel coupling a reaction vessel to an ion generating device, an actuator coupled to the plurality of ion generating devices to thereby allow movement of the plurality of ion generating devices, and a mass spectrometer
