Nickel Skimmer Cone for x-lens (G3280-67041) ¿ For Agilent 7700x/7800/7850/8800 ICP-MS. Standard cone used x-lens and suitable for most common applications (e.g., routine aqueous environmental samples, <5% acid matrix, non-HF, non-organic). Not for samples containing hydrofluoric acid (HF). Use 10x Magnifier Inspection Tool with Built-In LED Illumination (NC2042261) to inspect cone orifice condition. Use Skimmer ConeGuard (70-803-1008) to protect cone threads during cleaning. When not in use, keep cones stored in original packaging for protection.For corrosive acids, including HF, use Pt Skimmer with Cu Base for x-lens, P/N 501907590, must be mounted on brass adaptor skimmer base. For organic analysis, use Pt Skimmer with Ni Base for x-lens, P/N 501907591, which must be mounted on brass adaptor skimmer base. For lowest Ni background & laser ablation applications, use Al Skimmer for x-lens, see AT7702X-Al.Glass Expansion is ISO 9001:2015 certified by AB Certification, No. AU4501-9001
