QCell Collision Cell
Non-consumable thanks to off-axis tranfer of ion-beam into collision cell. Small cell volume for fast gas exchange, with switching and stabilization times of <10 s. Proprietary flatapole system providespowerful interference reduction for a clearer mass spectrum in all sample types.Unique design allows low mass ions to pass through the cell in He KED mode, enabling detection of Li, Be and B. Flexibility to work with reactive gases, such as mixtures of O2 , NH3 and H2
Ion Optics
The iCAP Q ICP-MS transfer lens system includes a unique 90° cylindrical ion lens providing high ion transmission across the entire mass range – the RAPID lens: Right Angluar Positive Ion Deflection. The open lens stack eliminates lens cleaning maintenance and a completely off-axis design together with QCell technology delivers a class leading background noise. Mass response is optimized for increased low mass sensitivity.
Electrical connection of ion optical lenses
All electrical connections to lenses inside the analyzer chamber are achieved via field proven, gold spring contacts mounted into the chamber lid, eliminating wiring and minimizing EMC issues and RF leakage. Detector Long lifetime detector designed for ICP-MS requirements. Dwell times of 100 μs in both detection modes. Linear dynamic detection range: >9 orders of magnitude accurately measures traces to major matrix ions in a single scan. One Click Setup for automated assessment and optimization of operating voltages and cross- calibration. Cradle design for ease of detector exchange.
Vacuum System
In the event of a power failure, high vacuum is maintained and them turbo pump automatically restarts as soon as power is restored. A stable vacuum obtained in less than 15 minutes pumping timem, enables fast return to service after routine maintenance.
Interface
Unique front opening interface provides rapid, simultaneous access to cones and extraction lens, to facilitate routine maintenance and minimizing downtime. Cones are rapidly removed by a single (magnetic) tool while the extraction lens is bayonet mounted for easy handling.
Cones Field proven sample cones with 1.1 mm diameter orifice for minimal deposition when analyzing high matrix samples. Solid Ni construction as standard, Pt tipped as option (standard on iCAP Qs) for increased durability. With optimized skimmer tip operating temperature and narrow 0.5 mm orifice for protection of the subsequent lens stack, matrix deposition is minimized and maintenance reduced. Proprietary skimmer insert design reduces memory effects and a range of choice
of inserts allow the user to balance the needs of matrix resistance
against absolute sensitivity.
Extraction Lens
Single extraction lens operated at low voltages for optimum ion extraction and focusing before entry into the RAPID lens.
Interface Pump
External, high performance pump to provide backing to the turbo pumps and evacuation of the expansion region for improved sampling from the plasma. Supplied with synthetic, chemically stable, temperature resistant rotary pump oil as standard.
Slide valve
PC controlled. Defaults to closed position when plasma is off or in the event of a power failure, maintaining vacuum in the analyzer housing.
