Description
UHPLC Guard Columns NUCLEODUR® C18 Gravity, 1,8 µm, 4 x 3 mm are short protective columns intended for ultra-high-performance liquid chromatography. They sit upstream of the analytical column to intercept particulates and strongly retained matrix components before those reach the main bed, helping preserve peak shape and system pressure stability in reversed-phase work. The C18 Gravity chemistry matches common NUCLEODUR® C18 Gravity analytical phases, so selectivity remains consistent when the guard is exchanged. Particle size is 1,8 µm and the hardware format is 4 x 3 mm, a compact geometry suited to modern UHPLC flow paths and limited extra-column volume. Each pack contains 3 pc(s), giving laboratories ready replacements for routine method sequences without interrupting instrument scheduling. These units come from manufacturer MACHEREY-NAGEL and integrate into established NUCLEODUR® UHPLC setups used across pharmaceutical, environmental, and life-science laboratories. Approximate pack weight is 0,019 kg, so storage beside the chromatograph is straightforward. Deploy them wherever C18 Gravity UHPLC methods already run and a matched guard is required to extend analytical-column service life under high-pressure conditions.
This article belongs on HPLC guard columns, in HPLC columns & accessories.

Questions about UHPLC Guard Columns NUCLEODUR®, C18 Gravity, 1.8µm, 4x3mm, 3 unit(s)
What is this article?
UHPLC Guard Columns NUCLEODUR®, C18 Gravity, 1.8µm, 4x3mm, 3 unit(s) is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in HPLC guard columns, inside HPLC columns & accessories, in Chromatography equipment.
A guard column is a short column of the same phase as the analytical column, placed in front of it to catch particles and compounds that would stick forever. It is meant to be replaced. A guard of a different phase changes the separation. The holder and the cartridge are often separate parts.
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.
