Common HPLC accessories are consumables and spare parts required for the daily operation and maintenance of a High-Performance Liquid Chromatography (HPLC) system. These include items such as fittings, filters, vials, and columns.
Fittings and tubing
These accessories ensure a leak-free, high-pressure flow path for the mobile phase and sample.
PEEK Fittings: These are chemically inert and biocompatiable, making them ideal for applications that require a metal-free flow path. Brands like VICI and IDEX Health Science offer various PEEK fittings, unions, and ferrules.
Stainless Steel (SS) Fittings: These are extremely robust and are used for very high-pressure applications. Supelco offers stainless steel HPLC fittings for 1/16 inch tubing.
Tubing: PEEK tubing is used for biocompatible systems, while stainless steel is for high-pressure setups.
