Nickel Sampler Cone, 100% Nickel (3004661), standard sampler cone made from 100% nickel providing lowest Cu background for Thermo X Series ICP-MS. Suitable for most common applications (e.g., routine aqueous environmental samples, <5% acid matrix, non-HF, non-organic). Use a new Graphite Sampler Cone Gasket (TG5001) each time the cone is re-installed, even if it’s the same cone. Use 10x Magnifier Inspection Tool with Built-In LED Illumination (NC2042261) to inspect cone orifice condition. When not in use, keep cones stored in original packaging for protection.For more efficient heat transfer use Nickel Sampler with Copper Core, 501694614. As acid concentrations begin to exceed 5%, and for samples containing hydrofluoric acid (HF), and other highly corrosive samples, we recommend platinum cones, see TG1026A-Pt/Cu. For lowest Ni background and laser ablation applications see TG1021-Al.Glass Expansion is ISO 9001:2015 certified by AB Certification, No. AU4501-9001
