Used VARIAN AA-220FS #9394488 for sale

VARIAN AA-220FS is a high performance atomic absorption spectrometer for detection of metals in a wide variety of elemental solutions. This state-of-the-art equipment uses a double-beam optical design for fast, accurate and reliable streaming sample analysis. It uses a powerful xenon flash lamp for high-intensity excitation in both absorption and fluorescence modes. The two-lamp design enables complete separation of the excitation and emission beams and extends the lifetime of the lamps. The absorbance mode has a spectral bandwidth of up to 220 nm. A unique capability of AA-220FS is the asymmetric slit design, which eliminates cross-talk between adjacent channels. This eliminates the need for manual calibration and further increases the analytical accuracy and sensitivity. The spectrometer has a high intensity Xe excitation source and a CCD detector for improved sensitivity. VARIAN AA-220FS provides multiple operating modes, including background correction, internal and external standards, and automatic reproducibility checks. The system also offers automatic optimization of absorption methods and trace analysis capabilities. The unit features VARIAN SAMS (Sample Angle Measurement Machine) software for easy and accurate sample loading. This software allows users to adjust the sample angle for maximum sensitivity. The software also stores methods and enables users to export measured results for printing and analysis with other applications. The user interface is a high-resolution color touchscreen that offers easy control over testing and setup menus. The intuitive layout of menus and procedures make AA-220FS easy to use even for inexperienced users. The spectrometer is also highly upgradable. Users can install additional tool cards or add optional optical filters, enabling analysis of additional elements or substances. VARIAN AA-220FS is a reliable and sophisticated spectral instrument that combines high performance with outstanding usability. It is an excellent choice for labs in need of reliable and accurate elemental analysis.
