The Orbitrap is an ion trap mass analyzer that consists of two outer electrodes and a central electrode, which enable it to act as both an analyzer and detector. Ions entering the Orbitrap are captured through "electrodynamic squeezing," after which they oscillate around the central electrode and in between the two outer electrodes. Orbitrap ID-X Tribrid MS conditions Ion Source Orbitrap MS ESI pos. = 3500V Method 1—LC-MS ESI neg.

Thermo Orbitrap have the best Resolving power: 70,000 at m/z 200. Qtof have 40,000. The Orbitrap-MS detectors are one of the most common HRMS analyzers belonging to the Fourier transform MS family, characterized by increased higher resolving power, sensitivity, and mass accuracy. These detectors are based on the confinement of ions in an electrostatic potential.

The typical LC-MS methodologies involve use of LC-MS/MS technology, also referred to as triple quadrupole mass spectrometers.

doi: 10.1016/j.watres.2019.05.099. Background: Saliva samples collected from one 58 year old male and one 35 year old female during 7 days of fasting were analyzed by direct immersion of both C18 and mixed-mode biocompatible solid-phase microextraction fibers, in combination with a LC–MS method using a benchtop orbitrap instrument in both positive and negative ionization modes Dedicated for Thermo Scientific ™, the LC / MS Bench BCH19088 for Thermo Scientific ™ Orbitrap Exploris ™ 120 – Thermo Scientific ™ Orbitrap Exploris ™ 240 and Thermo Fisher ™ Orbitrap Exploris ™ 480 includes noise reduction enclosure, vibration dampening system and many other features to improve your LC / MS performance. The LC/MS platform also needs to offer high sensitivity and wide dynamic range for both MS and MS/MS in order to detect and quantify both low abundance and high abundance lipid species. The high resolving power offered by the Orbitrap analyzer in combination with HR/AM enables a wide range of lipid identification and precise quantitation from complex biological samples.
