Used THERMO SCIENTIFIC Q Exactive #293642265 for sale

THERMO SCIENTIFIC Q Exactive is a high-performance mass spectrometer designed for the characterization of biomolecules and small molecules. It combines a hybrid quadrupole-orbitrap mass analyser to provide accurate mass and fragmentation data over a dynamic range of up to several orders of magnitude. The instrument also features a linear ion trap that can be used to further fragment molecules. Its high sensitivity and exceptional accurate mass resolution make it an ideal choice for a wide range of MS/MS applications such as targeted proteomics, small molecule characterization, metabolomics and peptide sequencing. Q Exactive utilizes the latest in high-resolution mass spectrometry technology. Its hybrid quadrupole-orbitrap design combines a quadrupole-based mass analyser, which operates by selecting a single mass-to-charge (m/z) ratio from the ionized molecules, and an orbitrap analyser, which utilizes a sinusoidal RF field to trap ions and then measure them as they oscillate in the trap for a known period of time. The mass analyser is capable of providing high-resolution accurate mass data (in the ppm range) across a wide dynamic range and is especially suited for the analysis of low concentrations of analytes and those with large m/z values. Combining the quadrupole-orbitrap with a linear ion trap further enhances spectral information. This allows the instrument to perform higher-energy collision dissociation (HCD) to generate further fragmentation information and peptide sequence information. THERMO SCIENTIFIC Q Exactive is a highly sensitive device with a detection limit better than 10-12 moles, and a dynamic range of up to five orders of magnitude. Furthermore, it has a maximum scan speed of 70,000 m/z per second, allowing it to acquire complex scans in a timely manner. Its 16-bit ADC resolution provides high-definition data, while the autosampler streamlines sample introduction. Finally, the instrument is user-friendly, with an easy to use graphic-user-interface and a wide range of available software packages, such as THERMO SCIENTIFIC Xcalibur software, for data collection and analysis. Overall, Q Exactive is a high-performance, accurate mass spectrometer designed for the characterization of biomolecules and small molecules. Its hybrid quadrupole-orbitrap mass analyser provides high-resolution data over a wide dynamic range, while its linear ion trap enables additional fragmentation information. Furthermore, it has a high sensitivity, a maximum scan speed of 70,000 m/z per second, and a 16-bit ADC resolution. All these features make THERMO SCIENTIFIC Q Exactive ideal for a wide range of MS/MS applications such as targeted proteomics, small molecule characterization, metabolomics, and peptide sequencing.
