Used BECKMAN COULTER 951A #293621219 for sale

BECKMAN COULTER 951A is a residual gas analyzer (RGA). It is specifically designed to allow precise detection and analysis of very low concentrations of gas molecules in vacuum systems. It is able to measure residual gases from atmospheric pressure down to torr-level vacuum. The main components of 951A are designed to maximize sensitivity, accuracy and temperature stability. It has an ionization chamber, with a high voltage power supply and electrostatic filter to isolate ions and contaminants. The detector is constructed of a field-effect transistor (FET) base and several detectors mounted inside the ionization chamber. Inside the chamber, electrons are generated by a hot filament and collisions between the detector and the gas molecules take place. Due to its advanced technology, BECKMAN COULTER 951A is able to accurately measure a variety of gases and gas concentrations. With a mass range of up to 243 atomic mass units, this RGA is suitable for analysis of a variety of applications, including residual gases in clean room, on electronic components, and for pharmaceutical and medical applications. 951A is equipped with the latest and most advanced features, including Auto-Analysis Mode and process monitor technology. Auto-Analysis Mode allows automatic analysis of full analytes, while process monitor technology allows periodic analysis to ensure analytical accuracy and traceability of processes. In addition, BECKMAN COULTER 951A is reliable, easy to use and offers a wide range of analytical capabilities. With its high-accuracy and highly sensitive measurement performance, it is an ideal product for monitoring process related substances, as well as a wide variety of analytical applications. Furthermore, 951A can be connected to computers for immediate analysis and data storage.
