Interface Cones for 7500 ICP-MS from Agilent
A high quality plasma/vacuum interface design has a large effect on the overall performance and sensitivity of an ICP-MS system. Interface cones are key elements of this and Agilent's range of sampling and skimmer cones ensures that positive ions produced in the plasma are extracted into the vacuum system effectively every time. Agilent's platinum and nickel interface cones provide the level of performance that the 7500 ICP-MS range demands.
Features
- Nickel sampling cones with a copper base are available as well as sampling and skimmer cones for T-mode
- Nickel skimmer cones for the ICP-MS 7500 a/i/s systems are available. Note that the point of the skimmer cone is easily deformed and a deformed cone will greatly affect performance. In addition, if the O-ring becomes stuck, wipe it gently with methanol.
- Platinum sampling cone with a copper base (in both standard and 18 mm models) can be provided
- Platinum skimmer cones, with a copper base, for the ICP-MS 7500 a/i/s systems are also available. These cones must be mounted on a brass skimmer base.
- Skimmer and sampling cones with both platinum and nickel bases are available that are unique to the ICP-MS 7500c system
