Sample Injector Valve Component RTP Company End-Use Case Study Scientific Instrument Application for RTP PEEKTM Compound A PEEKTM compound, using the material’s outstanding combination of strength, dimensional stability and inertness, is the material of choice for a scientific instrument application. Rheodyne, Inc. Cotati, California, makes syringe loading sample injector valves. These are used for commercial high performance liquid chromatography (HPLC), a system that analyzes chemical compounds. RTP 2201 (a modified/reinforced PEEKTM) is used in the “stator” component of the sample injector valve. The part has six threaded tubing ports, allowing connection to other components of the HPLC system. Conventional stators use stainless steel. With an inert PEEKTM stator, the sample fluid strea
