Ion Lenses for 7700/7800/7900 and 8800/8900
Ion Lenses for 7700/7800/7900 and 8800/8900 from Agilent
Agilent manufactures a range of high quality ion lenses for use with the market-leading ICP-MS portfolio. Electrostatic ion lenses keep ions focused in a compact "ion beam" as they pass through the vacuum system to the final chamber, where the mass spectrometer and detector are housed. The ion lenses also separate ions from photons and residual neutral material. The use of an “off-axis” ion lens arrangement gives higher ion transmission across a wider mass range compared to alternative configurations. The off-axis design does not use a photon stop, so there is much higher overall ion transmission through the instrument. A range of components and accessories are also available.
- High transmission off-axis or omega lens arrangement that separates the positively charged ions from the photons and neutral particles
- The extraction lenses are placed just behind the skimmer cone and mounted on the skimmer base. They are used to extracts positive ions and accelerate them to the Einzel lens.
- The omega lens is a block of 5 lenses (omega bias, omega (+), omega (-), QP focus and plate bias) and separates photons and ions, steering ions onto the quadrupole MS.
- Screw and spacer sets are available for extraction or omega lenses
- A variety of additional components and consumables are available: lens cleaning and polishing kits, octopoles and octopole assembly equipment as well as tubing for reaction gas
