Platinum Sampler Cone with Copper Core (3601289), for Thermo Q/RQ/TQ and X Series ICP-MS. Suitable for most applications, including corrosive samples (e.g., routine aqueous environmental samples, >5% acid matrix, HF, organic). Although the highest cost option, it is typically the most durable, longest-lasting, and because it runs hotter it requires less frequent cleaning. 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 common applications with <5% acid matrix, non-HF, non-organic, see catalog number 501694614. For lowest Ni background and laser ablation applications, see catalog number TG1021-Al.Glass Expansion is ISO 9001:2015 certified by AB Certification, No. AU4501-9001
