Used BECKMAN COULTER 864 / 865 Series #9199722 for sale

BECKMAN COULTER 864 / 865 Series Residual Gas Analyzers (RGAs) are specialized instruments specifically designed to measure order-of-magnitude changes in gas concentrations in hostile, high-vacuum environments. These robust instruments are resistant to physical shock, chemical corrosion, and extreme temperature conditions, allowing them to operate reliably in extreme environments where other analytical equipment fails. 864 / 865 Series RGAs use a combination of direct current (DC) and alternating current (AC) spectroscopy techniques to analyze gas. The instruments utilize a heated, filament-based ion source to liberate atoms of the gas species from the sample gas and an electron multiplier for subsequent detection of the liberated atoms. The signal is then processed and presented as an electrical output signal. The 865 models also feature a photomultiplier for the detection of molecular fragments and/or radioactive isotopes. BECKMAN COULTER 864 / 865 Series RGAs have powerful quadrupole and variable radius filters, allowing precise spectroscopic selection of finite gas populations, such as molecular fragments, isotopes, and different elements or their compounds. These period-rating filters are designed to create a narrow frequency resonance window that maximizes the RGA's sensitivity and selectivity, ensuring accurate gas measurement in hostile environments. In addition to superior measurement performance, 864 / 865 Series RGAs feature advanced software functions which allow for safe and secure operation. These software functions enable users to initiate multiple acquisition and analysis sequences in response to exceptional gas events, as well as control instrument parameters, record and store data, and archive reports. BECKMAN COULTER 864 / 865 Series of RGAs is an ideal solution for accurately measuring gas concentration in challenging environments. These instruments are able to withstand harsh operating conditions due to their robust design, and are capable of precise measurements due to their quadrupole and variable-radius selection filters. Their advanced software functions increase user safety and allow for secure operation.
