Nickel Sampler Cone (W1033612) ¿ Standard sampler cone for PerkinElmer NexION 1000/2000/5000/300/350 ICP-MS. Suitable for most common applications (e.g., routine aqueous samples, <5% acid matrix, non-HF, non-organic). Not recommended for samples containing HF. Replace Sampler Cone Gasket each time the cone is installed, even if it is the same cone (501907691). 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. Use Sampler ConeGuard to protect cone threads during cleaning, 70-803-1024.For corrosive samples, including HF, use Platinum Sampler Cones, see catalog number 501907686. For lowest boron background, we recommend Boron-Free Platinum Sampler Cones, see catalog number 501907687.Glass Expansion is ISO 9001:2015 certified by AB Certification, No. AU4501-9001
