Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 7890 / 5977B / 7697A #293766588 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 7890 / 5977B / 7697A is a sophisticated gas chromatography-mass spectrometry (GC-MS) equipment that combines the capabilities of a gas chromatograph with a mass spectrometer to enable precise and accurate chemical analysis of complex mixtures. This high-performance analytical instrument is widely used in various industries, including pharmaceuticals, environmental monitoring, food safety, and forensic science, for its reliability, sensitivity, and efficiency in detecting and identifying compounds with high precision. HP 7890 / 5977B / 7697A system consists of three main components: the GC module (7890), the MS detector (5977B), and the sampler (7697A). The GC module is responsible for separating the components of a sample into individual compounds based on their chemical properties through gas chromatography. The MS detector then ionizes and detects these separated compounds based on their mass-to-charge ratio, providing qualitative and quantitative information about the composition of the sample. The 7890 GC module features advanced capabilities for temperature control, flow rate management, and inertness to ensure optimal separation of compounds in complex mixtures. It utilizes various separation modes, such as liquid injection, headspace analysis, and thermal desorption, to accommodate different sample types and matrices. Additionally, the modular design of the GC unit allows for easy integration with other analytical techniques or accessories for enhanced versatility in analytical workflows. The 5977B MS detector is equipped with a high-resolution quadrupole mass analyzer that offers exceptional sensitivity and selectivity in detecting trace levels of compounds in complex samples. It operates in electron ionization (EI) and chemical ionization (CI) modes to ionize molecules and generate mass spectra for compound identification. The mass range of the detector covers a wide range of molecular weights, enabling analysis of small molecules to large biomolecules with high accuracy and precision. The 7697A sampler is a versatile autosampler that automates sample introduction and injection into the GC machine, increasing sample throughput and minimizing human error. It features a wide range of sample introduction techniques, including liquid injection, solid-phase microextraction (SPME), and headspace analysis, to accommodate diverse sample types and volumes. The sampler's precise injection mechanism and sample handling capabilities ensure reproducible and reliable results in routine and high-throughput applications. Overall, AGILENT 7890 / 5977B / 7697A GC-MS tool is a powerful analytical tool for qualitative and quantitative analysis of complex samples in various fields of research and industry. Its combination of advanced technologies, modular design, and automation capabilities makes it an indispensable instrument for laboratories seeking to achieve high analytical performance, efficiency, and reliability in their chemical analysis workflows.
