CPI skimmer and sampler cones for popular ICP-MS instrumentation are the choice of leading instrument OEM's and are guaranteed to meet or exceed your expectations. These highly precise components are produced using a proprietary combination of electroforming and CNC machining techniques. This allows the ability to produce the sharpest hole edges, highest surface finishes and perfectly tapered holes, all of which help minimize gas disturbances and improve analytical performance. Our cones also feature a unique copper core cooling technology to conduct heat away from the tip, preventing melting or burning due to the low thermal conductivity of nickel and thus greatly extending peak sensitivity and cone lifetime. You will be impressed with the quality and performance of these industry-leading products.
