Agilent, G8400-67201, 7900, 8900 with x-lens ICP-MS skimmer cone, Platinum with Copper base. Optional cone used with x-lens for aggressive acid digests, including HF

Agilent Platinum Skimmer Cone with Copper Base is an ICP-MS interface component for 7900 and 8900 systems fitted with an x-lens. The cone uses a platinum tip and copper base and is intended for challenging acid-digest applications, including samples containing hydrofluoric acid. It is an optional skimmer cone, not the sampler cone or skimmer base. The specified assembly uses a platinum sampler cone and the appropriate brass skimmer base. Interface cone condition matters because deposits, erosion or mechanical damage can alter ion transmission and analytical sensitivity. Inspect the cone opening, tip and sealing surfaces during scheduled maintenance. Apply suitable cleaning and handling procedures to avoid scratching the platinum surface or contaminating the interface. After replacement, check vacuum performance, tune the mass spectrometer and verify sensitivity using relevant standards. Match the cone to the x-lens interface before ordering; other lens arrangements may require different parts. Handle HF-containing residues with the controls appropriate to that hazard.
