Platinum Skimmer Cone, H, Boron-Free (1047460) ¿ For Thermo/Finnigan Neoma MC-ICP-MS, Element 1, 2 & Neptune. Ideal for lowest boron background and semiconductor applications, including corrosive samples (e.g., routine aqueous environmental samples, >5% acid matrix, HF, organic). Although the highest cost option, it is typically the most durable, longest-lasting, and because it runs hotter it requires less frequent cleaning. Use 10x Magnifier Inspection Tool with Built-In LED Illumination (NC2042261) to inspect cone orifice condition.
