Nickel Sampler Cone for x-lens (G3280-67040) ¿ For Agilent 7700/7800/7850/7900/8800/8900 ICP-MS. Standard cone used with 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. When not in use, keep cones stored in original packaging for protection.For corrosive acids, including HF, use Pt Sampler with Ni Base, P/N 501907586. For high TDS samples causing rapid cone deposition, use Pt Sampler with Ni Base, P/N 501907585. For lowest Ni background & laser ablation applications, use Al Sampler, see AT7701-Al.Glass Expansion is ISO 9001:2015 certified by AB Certification, No. AU4501-9001
