Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 7890A #293766599 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 7890A is a high-performance gas chromatograph that uses a quadrapole mass spectrometer (QMS) detector to identify and quantify a wide range of chemical compounds in the gas phase. This dual-channel configuration allows the user to quickly and accurately analyze complex samples. HP 7890A is designed to meet high levels of performance and quality while still providing cost-effective operation. The instrument utilizes an electron impact (EI) ionization source to form an ionic species of a molecular in the sample. The ions are then focused and collected in an ion trap assembly and a charged rod system. The ions are scanned by a computer-controlled scan that determines the ions' mass-to-charge ratio (m/z) and abundance distribution. The resulting information is utilized to generate a chromatogram. AGILENT 7890A is capable of producing sub-ppm (parts-per-million) sensitivity for a range of sample types, such as hydrocarbons, hydrocarbon derivatives, volatile organic compounds (VOCs) and a variety of other gas-phase compounds. HEWLETT-PACKARD 7890A's scan speed is adjustable over a wide range. It features computer-controlled scan speeds as fast as 1,000 scans per second. Additionally, the instrument is capable of performing up to 10,000 scans per second in peak sharing mode. This feature allows multiple compounds to be analyzed simultaneously, reducing sample analysis time. The active window of 7890A's scan range is adjustable from 10 to 1000 daltons (Da). The instrument also offers a wide dynamic range with the ability to measure mass with an accuracy of 0.1 per cent. Also available is a scan rate range of 0.001 to 500 m/z s-1. KEYSIGHT 7890A is also equipped with an Autosampler system, data handling and processing software, and GC column selection technology. The Autosampler allows users to acquire repeatable accurate measurements of volatile and non-volatile samples. The Autosampler design also reduces wasted sample time by allowing the user to load samples in batches and set custom sampling protocols. The data handling and processing software allows users to quickly and accurately analyze sample data, as well as configure and control the instrument. AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 7890A also provides a number of additional accessories for a range of applications and additional power optimization options to ensure optimal performance. In summary, HP 7890A is a high-performance, cost-effective spectrometer built for the user who needs to accurately and quickly analyze complex samples. It is specifically designed for use in volatile sample analysis, VOCs, and other gas-phase compounds. With software for data handling and processing, as well as Autosampler capabilities, and a wide scan range, AGILENT 7890A provides an ideal solution for a range of applications.
