WebAn ion trap is a combination of electric or magnetic fields used to capture charged particles known as ions often in a system isolated from an external environment. Ion traps have a number of scientific uses such as mass spectrometry, basic physics research, and controlling quantum states. Web23 aug. 2006 · Ion trap/time-of-flight hybrid mass spectrometers are powerful tools for the detailed structural analysis of modified peptides. We have analyzed Met-Lys-bradykinin modified with deoxycholate at the amino-terminus or the ε-amino group as model peptides.
WebA microfluidic-based nanoflow LC interfaced to an ion trap mass spectrometer with ETD, or a QTOF mass spectrometer were used to analyze the samples. Fluoranthene was used as the chemical reagent for ETD. All ETD and CID data were analyzed using Spectrum Mill Protein Identification Workbench. WebIon trap, shown here is one used for experiments towards realizing a quantum computer. An ion trap is a combination of electric and/or magnetic fields used to capture charged particles — known as ions — often in a system isolated from an external environment.
