Platinum Sampler Cone with Nickel Plated Base (G3280-67142) ¿ For Agilent 7700/7800/7850/7900/8800/8900 ICP-MS. For use with aggressive acid matrices (e.g., HCl, HF, HClO4) and high matrix samples. Use with platinum skimmer cone and brass skimmer base. 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 x-lens, use P/N 501907575. For high TDS samples causing rapid cone deposition, use Pt Sampler with Ni Base, P/N 501907585 or 501907583. 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
