Used THERMO FINNIGAN LTQ #293829174 for sale

THERMO FINNIGAN LTQ (Linear Ion Trap-Orbitrap) is a state-of-the-art mass spectrometer designed for advanced identification and quantification of small molecules. It is a true hybrid instrument utilizing a variety of analytical techniques in a single system. LTQ utilizes linear ion trap mass spectrometry (MS/MS) and Orbitrap mass spectrometry (MSn) to detect, identify and quantify compounds with capabilities of high resolution, abundant spectra and unmatched precursor ion selection. THERMO FINNIGAN LTQ publishes accurate mass and high resolution data, allowing identification and quantification of many compounds with fewer false positives. LTQ is composed of several modular components. The first component is the ion source, where molecules of interest are ionized by electron impact, chemical ionization, or electrospray or a combination of all three. Next, ions are transferred to the ion trap, which stores and isolates the positively or negatively charged ions. After isolation, multiple fragmentation techniques, such as Collision-Induced Dissociation (CID), energy-resolved Dissociation (ERD), and electron-capture Dissociation (ECD) can then be employed by the ion-trap. Additionally, THERMO FINNIGAN LTQ utilizes multiple, linear mass filters (mass analyzers) to detect and identify sample components. The Orbitrap, which is comprised of an external, circular coil and a central Titan pole-piece, provides high-resolution mass spectra for accurate mass determination. The Orbitrap also enables enhanced detection and quantification capabilities. LTQ is an exceptionally versatile instrument offering a variety of analytical capabilities, including accurate mass determination, detection of isomers, compound identification, absolute quantification, quantification of sample metabolites and trace impurities, and the identification of unknowns. Its multiple components, including a linear ion trap, a state-of-the-art Orbitrap mass analyzer and a variety of ionization sources, make it a premier advanced research and ad hoc analytical tool. As such, THERMO FINNIGAN LTQ provides powerful capabilities for research, industrial and government markets, often at a fraction of the total cost of ownership of other MS systems.
