Used FINNIGAN AS #9126322 for sale

FINNIGAN AS is an atmospheric pressure ionization (API) mass spectrometer that has been designed for the characterization and identification of complex volatile organic compounds (VOCs). It utilizes a fast electro-spray ionization (ESI) source coupled with a high-resolution, quadrupole mass analyzer and time-of-flight (TOF) detector. The data acquisition rate and sensitivity of the instrument are extremely high, enabling an efficient, high-throughput analytical process for the rapid identification and characterization of VOCs in complex sample matrices. It is equipped with two distinct sources, an ESI source and a Curtain-type Corona Desolvation source. These sources enable the detection of a wide range of compounds, including small molecules, macromolecules, and non-volatile species. The ESI source utilizes a high-frequency, electrically charged spray for the ionization of volatile compounds, producing positively charged ions. The ion cloud is driven through the skimmer by a nebulizer gas, and its expansion is focused by the skimmer before entering the quadrupole mass analyzer. The mass analyzer functions by passing the charged ions through a high voltage applied between four steel rods in order to filter out all ions except those with a particular m/z ratio. During the desolvation of the ESI droplets within the Curtain-type Coron Desolvation Sousce, volatile and semi-volatile compounds are evaporated in order to form non-stabilized ions, which can be detected in the TOF detector. AS has a high-resolution, digital TOF detector which uses coincidence detection to discriminate charged ions based on their energy and charge divergence. The TOF detector has a high data acquisition rate and sensitivity, enabling an extended linear dynamic range for the detection of low concentrations of compounds. The ESI source is further configured with active channel focusing which adjusts the skimmer's slit aperture for optimal resolution and sensitivity. The system is equipped with an advanced software package, allowing users to easily manipulate, analyze, and store data. It also offers an easy to use graphical user interface to simplify the daily operation and provide an improved work flow. In conclusion, FINNIGAN AS is an advanced API mass spectrometer that enables the fast and efficient identification and characterization of volatile organic compounds (VOCs) in complex sample matrices. It utilizes a fast ESI source, a high-resolution quadrupole mass analyzer and a high-sensitivity and high-resolution TOF detector to provide efficient and accurate results. In addition, it is equipped with a powerful software package to allow for easy manipulation, analysis, and storage of the data.
