Thermo Finnigan LXQ Mass Spectrometer System

The Finnigan LTQ has been powered on and cannot be tested for full functionality due to lack of software. Unit looks new, is clean and has no cosmetic damage. 

The Finnigan LTQ is the latest innovation in the well-established Finnigan ion trap mass spectrometers. Based on novel design features including a hyperbolic segmented linear ion trap, dual detectors, radial ion ejection, and state-of-the-art electronics, the Finnigan LTQ redefines performance. The culmination of these features enables more experiments, leading to greater coverage on less sample in less time.

The Finnigan LTQ incorporates the rugged Ion Max source (not included), allowing simple switching of ionization probes. The exceptional ion transmission achieved with the Ion Max source, combined with the increased ion storage capacity of the linear ion trap, novel ion ejection and detection technology, makes the Finnigan LTQ the most sensitive LC/MSn instrument available today.

The LTQ is a member of the Finnigan family of MS detectors. The Finnigan LTQ MS detector is an advanced analytical instrument that includes a syringe pump, a divert/inject valve, an atmospheric pressure ionization (API) source, an MS detector, and the Xcalibur data system. In a typical analysis, a sample can be introduced in any one of the following ways:

• Using the syringe pump (direct infusion)
• Using the inject valve fitted with a loop and an LC pump (flow injection analysis)
• Using a valve and an LC system fitted with a column (LC/MS)

In analysis by LC/MS, a sample is injected onto an LC column. The sample is then separated into its various components. The components elute from the LC column and pass into the MS detector where they are analyzed. Analysis by direct infusion or flow injection provides no chromatographic separation of components in the sample before it passes into the MS detector. The data from the MS detector is then stored and processed by the Xcalibur data system.
