Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 6550A QTOF #293817524 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 6550A QTOF (quadrupole time-of-flight) spectrometer is a powerful instrument used for mass spectrometry analyses in a wide range of scientific research fields, such as pharmaceuticals, proteomics, metabolomics, environmental analysis, and more. This state-of-the-art spectrometer combines high-resolution mass spectrometry capabilities with accurate mass measurement and fast data acquisition rates, making it a versatile tool for both qualitative and quantitative analysis of complex samples. The key components of HP 6550A QTOF spectrometer include an electrospray ionization (ESI) source, quadrupole mass filter, collision cell, flight tube, and time-of-flight detector. The ESI source ionizes the sample molecules, which are then introduced into the quadrupole mass filter for mass selection and ion focusing. The collision cell allows for fragmentation of selected ions to generate structural information, while the flight tube and time-of-flight detector measure the time it takes for ions to travel through the tube, allowing for accurate mass determination based on their flight times. One of the main advantages of AGILENT 6550A QTOF spectrometer is its high mass resolution and accuracy, which enable the detection and identification of compounds with exceptional precision. The instrument is capable of resolving complex mixtures and distinguishing between closely related compounds based on their mass-to-charge ratios. This high-resolution capability is essential for applications such as metabolomics, where the identification of metabolites in biological samples requires accurate mass measurements to differentiate isobaric molecules. 6550A QTOF spectrometer is also known for its high sensitivity, allowing for the detection of low abundance analytes in complex matrices. The instrument has a wide dynamic range, spanning several orders of magnitude, which is essential for the quantitation of compounds present in varied concentrations within a single sample. This versatility makes the spectrometer suitable for a wide range of applications, from targeted quantitation of specific analytes to untargeted screening of unknown compounds in complex samples. Another important feature of HEWLETT-PACKARD 6550A QTOF spectrometer is its fast data acquisition capabilities. The instrument can acquire mass spectra at high speeds, enabling rapid analysis of samples and increasing throughput in analytical workflows. The fast data acquisition rates are particularly useful for applications requiring real-time monitoring or high-throughput screening, such as drug metabolism studies or environmental analysis. In summary, KEYSIGHT 6550A QTOF spectrometer is a versatile and high-performance instrument that offers high resolution, accuracy, sensitivity, and speed for mass spectrometry analyses. With its advanced capabilities, the spectrometer is well-suited for diverse applications in research, pharmaceutical development, environmental testing, and other fields requiring precise and reliable mass analysis of complex samples. Its robust design, user-friendly interface, and integration with data analysis software make it a valuable tool for scientists and researchers seeking to push the boundaries of mass spectrometry analysis.
