Used THERMO FISHER SCIENTIFIC LTQ Orbitrap Velos #293823074 for sale

THERMO SCIENTIFIC LTQ Orbitrap Velos is an advanced Fourier-transform ion cyclotron resonance (FT-ICR) mass spectrometer. FT-ICR mass spectrometers are the most precise and sensitive spectrometers available and are used in numerous applications such as proteomics, metabolomics, glycomics, lipomics and small molecule characterization. LTQ Orbitrap Velos combines the ultra-high resolution, accurate mass and speed of Orbitrap technology with the sensitivity of multiplexed ion trap mass spectrometry (ITMS) to deliver unparalleled performance in LC-MS/MS studies. The instrument consists of several components that work together in sequence to generate a detailed analysis of the sample. First, the sample is ionized in an ion source. It can be ionized using electrospray ionization (ESI) or matrix-assisted laser desorbtion ionization (MALDI). Once the ions are generated, they are directed towards the front end of the instrument, which includes an ion trap and a quadrupole mass filter. These components are used to isolate and separate the ions according to their m/z ratio. The isolated ions are then directed to the Orbitrap analyzer, where they are subjected to Fourier transformation to determine their accurate mass. THERMO SCIENTIFIC LTQ Orbitrap Velos features ultra-high resolution and accuracy, with resolution up to 300,000 full width at half-maximum (FWHM). This resolution capability allows for the identification and quantification of metabolites, for example, since isomers can be easily distinguished due to the ultra-high resolution. The system also has an active orbital trapping technology that ensures the highest quality of analysis and eliminates the need for manual MS/MS flow optimization. Furthermore, it is equipped with an Automated Gain Control (AGC) feature, which adjusts the gain of the system to maintain the same signal-to-noise ratio throughout the scan. The instrument also has an integrated Flex Ion Source for automatic ESI source tuning. This feature allows for optimized source conditions and minimal source maintenance, resulting in improved sensitivity and resolution. In addition, the PtO-Liner desolvation interface helps reduce sample losses and improve ion transmission efficiency. Furthermore, the integrated nanospray probe helps fine tune and optimize the introductions of samples. LTQ Orbitrap Velos is optimized for triple quadrupole applications, enabling fast and accurate quantification of small molecules. It features optimal linearity and low limit of detection, as well as high mass accuracy, making it suitable for label-free applications and quantitative proteomics. THERMO SCIENTIFIC LTQ Orbitrap Velos also has an intuitive and user-friendly software package, making data acquisition and analysis quick and easy. Overall, LTQ Orbitrap Velos is an advanced mass spectrometer with many unique features and a wide range of applicability, making it an ideal tool for a variety of research applications.
