Nickel Sampler Cone (G1820-65238). For Agilent 4500/7500 ICP-MS. Standard cone used with a/i/c/ce/cs-lens. Suitable for most common applications (e.g., routine aqueous environmental samples, <5% acid matrix, non-HF, non-organic). Not recommended for samples containing hydrofluoric acid (HF). Use with Nickel skimmer cone and stainless steel base. Use 10x Magnifier Inspection Tool with Built-In LED Illumination (NC2042261) to inspect cone orifice condition. Use ConeGuard (70-803-1000) to protect cone threads during cleaning. When not in use, keep cones stored in original packaging for protection.For samples containing HF, and other highly corrosive samples where acid concentration begin to exceed 5%, we recommend a platinum cone, see catalog number 501907569.Glass Expansion is ISO 9001:2015 certified by AB Certification, No. AU4501-9001
