Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 6890A #293690406 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 6890A GCMS is a sophisticated gas chromatography-mass spectrometry instrument used for the separation and analysis of components of complex mixtures. The system is composed of two main components: the gas chromatograph (GC) and the mass spectrometer (MS). The GC portion of the instrument separates substances in a sample, while the MS detects and identifies them. HP 6890A provides high-performance gas chromatography with highly sensitive mass spectrometer technology. The GC features an oven that can hold up to six sample columns, which can range in length from 10 to 50 metres and feature internal diameters of 0.32 to 0.53 millimetres. The temperature of the oven can be programmed to a maximum of 400°C. The system can detect a wide range of compounds, from volatile and semi-volatile to heavy and polar. The GC is coupled to an excellent resolution MS that provides a high degree of sample analysis with high selectivity and sensitivity. It is equipped with a high-energy electron gun, with an energy range of 20-2800 eV, that ionizes the sample before being detected by the mass spectrometer. The MS component provides mass scans, in which the relative abundance of all constituents of a sample can be displayed, as well as focal scans to select a single target analyte. AGILENT 6890A has many other features including a low-level noise channel to achieve high sensitivity, an ultra-low noise autosampler, pressure and temperature control, and EI/CI/FSI change capabilities. It also features a control software system with a large number of user-defined options for data acquisition, analysis, and reporting. 6890A is a highly sensitive, robust instrument capable of providing accurate and reproducible data in a wide range of applications, from environmental and life sciences, to food safety and chemical analysis. With its high-performance GC and MS components, as well as its many user-defined options, it is an excellent choice for the analysis of complex mixtures.
