The Cirrus™3-XD Compact Benchtop and Rack-mounted Atmospheric Systems with V-lens™ Technology are designed for researchers and engineers who need to work beyond the limits of conventional quadrupole mass spectrometry gas analysis - to more easily detect and monitor trace gases - the Cirrus™ 3-XD Single-quadrupole MS Gas Analyzer delivers a unique analytical advantage for "eXtreme Detection" capability. The proven Cirrus™ Quadrupole MS platform now utilizes patented, V-lens™ ion optics with a double-focusing and deflection capability - to produce a consistently low baseline for any gas species - enabling trace level detection with greater clarity and confidence than ever before. With its versatile, compact design and powerful, automatable software control, the Cirrus™ 3-XD system provides a new level in performance, robustness and ease-of-use for the most challenging trace gas analyses. Cirrus™ gas analysis systems are ideal for on-line monitoring and analysis of gases and gas mixtures including trace contaminants in process gases, solvent vapors, hydrocarbons, atmospheric and inorganic gas species (including corrosives), freons and noble gases. Cirrus™ Single-quadrupole Mass Spectrometer Gas Analyzer systems are easy to install and operate, featuring automatic start-up and shut-down routines as well as built-in vacuum and heater interlocking for system protection. Cirrus™ 3-XD systems are manufactured from quality field proven materials which maximize reliability and uptime. Particular consideration has been paid to ease of service and maintenance.
