Copper Sampler Cone (211-90190-41, 220-95356-82) ¿ Standard low-cost copper sampler cone for Shimadzu 2030 ICP-MS. Suitable for most common applications (e.g., routine aqueous samples, <5% acid matrix, non-HF, non-organic). Not recommended for samples containing hydrofluoric acid (HF). Use a new Graphite Sampler Cone Gasket (SZ5001) 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 routine samples with better heat transfer, we recommend nickel sampler cone with copper base, see catalog number 501907697.For standard nickel sampler cone, see 501907696.For corrosive samples, including HF, we reccommend platinum sampler cones, see catalog numbers 501907701 (15 mm Pt insert), 501907702 (10 mm Pt insert).Glass Expansion is ISO 9001:2015 certified by AB Certification, No. AU4501-9001
