Used THERMO SCIENTIFIC LTQ Orbitrap #9121197 for sale

THERMO SCIENTIFIC LTQ Orbitrap spectrometer is a high resolution mass spectrometer that combines the sensitivity of an ion trap with an Orbitrap mass analyzer to provide superior analytical performance in high throughput applications. LTQ Orbitrap is ideal for sensitive and accurate analysis of large molecules such as proteins, peptides, nucleic acids, lipids, and low molecular weight metabolites. THERMO SCIENTIFIC LTQ Orbitrap uses a Thermo Fusion ion source with both electrospray ionization (ESI) and atmospheric pressure chemical ionization (APCI) sources to facilitate analysis of complex mixtures with minimal sample preparation. The collision cell of the spectrometer is operated with either a helium or nitrogen atmosphere, depending on the type of analyte being analyzed. This cell allows for the efficient generation of fragment ions to provide structural information about the sample molecule. The mass analyzer of LTQ Orbitrap is composed of a trap plus a hybrid travel quadrupole into an Orbitrap mass analyzer. The quadrupole acts as a pre-filter for the Orbitrap, allowing it to capture and identify ions with higher accuracy. The Orbitrap operates with high resolution and sensitivity to accurately determine the exact mass and charge state of a sample ion. This allows for the highly selective detection and identification of the analyte under study with unprecedented accuracy and linearity. THERMO SCIENTIFIC LTQ Orbitrap offers advanced data acquisition and statistical analysis capabilities, making it an ideal platform for the identification and quantitation of peptides, proteins, and metabolites in complex mixtures. Additionally, its automated internal calibration system ensures better repeatability and long-term system stability. LTQ Orbitrap spectrometer has been extensively used in a variety of applications such as metabolomics, proteomics, and pharmaceutical development for the analysis of samples from cells to biomarkers.
