Description
Graphite ferrules HP with 0,5 mm bore are precision sealing components for chromatography systems that use HP-style instrument connections. Made from graphite, they form a compressible, thermally stable seal around capillary columns and fittings in gas chromatography workflows. The 0,5 mm bore is intended to match common column outer diameters used in analytical GC, helping centre the column and support a leak-tight joint at injector and detector interfaces. Each pack contains 10 pieces, convenient for routine column installation and instrument maintenance. These ferrules from manufacturer Macherey-Nagel sit in the chromatography accessories category and are specified for connection to HP devices. Graphite construction combines the mechanical compliance needed for sealing with the heat resistance required under typical GC temperature programmes. Laboratories rely on correctly sized ferrules to maintain pneumatic integrity, reduce dead volume at the connection, and keep analytical performance consistent. Suitable for analytical chemistry, quality control, method development, and research environments operating HP-compatible GC hardware where reliable column fittings are essential day to day.

Questions about Ferrules, graphite, HP, 0.5 mm bore
What is this article?
Ferrules, graphite, HP, 0.5 mm bore is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in HPLC fittings, tubing & inline filters, inside HPLC columns & accessories, in Chromatography equipment.
HPLC fittings and tubing are numbered by bore. A wide bore after the column broadens the peaks. Finger-tight and wrench fittings, and stainless against PEEK, are different pressure ratings. An inline filter is the last screen before the column, and it clogs on purpose so the column does not.
An HPLC column is a tube packed, or coated, with a stationary phase. The sample is carried through it by a liquid, and the compounds leave at different times. The phase, the particle size, the length and the internal diameter decide the separation. A guard column is a short sacrificial piece in front of the analytical column. Fittings and tubing have a bore that either preserves the peak or smears it. Compound names follow IUPAC. Data are on PubChem. Method grades often cite the European Pharmacopoeia or USP.
