This O-ring forms the vacuum seal between the aluminum hyper skimmer cone and the interface housing on the NexION 300, 350, 1000, 1100 and 2000 ICP-MS. The hyper skimmer is the third cone in the NexION’s triple-cone interface, and a sound seal at this stage is essential to maintaining interface vacuum and consistent ion transmission into the ion optics. Replacing the O-ring at each cone change is routine preventive maintenance and avoids vacuum leaks that can appear as unstable signal or difficulty reaching operating pressure.
Molded from Viton fluoroelastomer for resistance to heat and chemical attack in the interface region, with an inner diameter of 0.614 in. and a cross-section width of 0.070 in. The same O-ring is also supplied in the 2400 Series II CHNS/O Elemental Analyzer maintenance kit (N2410152).
- Seals the aluminum hyper skimmer cone (W1033995), which is secured with the hyper skimmer screw (WE027484)
- Included in the NexION 300/350 Q/X/D (N8140513), NexION 300S/350S (N8140514), NexION 1000 (N8150058), NexION 2000B/C/P/S (N8150052, N8150055, N8150056, N8150057) and NexION 1100 (N8170104) consumable kits, 2 per kit
- For NexION 2200 and 5000 instruments, see hyper skimmer O-ring 09211389 (0.926 in. ID × 0.070 in. W)
