Description
UHPLC Guard Columns NUCLEODUR® C18 PAH with 1,8 µm particles and 4 x 3 mm dimensions protect ultra-high-performance liquid chromatography columns from particulates and strongly retained sample constituents. The fine particle bed matches modern UHPLC pressures and efficiencies, limiting early fouling of the main analytical column while maintaining sharp peak shapes. C18 PAH chemistry is intended for reversed-phase separations of polycyclic aromatic hydrocarbons and similarly hydrophobic compounds that require robust C18 selectivity under fast gradient or high-throughput conditions. The product is supplied as 3 pc(s) with a pack weight of 0,481 kg, suitable for laboratories that run frequent UHPLC sequences and need ready spare guards. Produced by MACHEREY-NAGEL within the NUCLEODUR® portfolio, these cartridges align with established silica-based UHPLC practice. The short 4 x 3 mm format keeps system volume low and installs easily on standard UHPLC hardware. Environmental, food-control, and research groups working with PAH-type analytes can use them to safeguard high-value sub-2 µm analytical columns without changing method chemistry.
This article belongs on HPLC guard columns, in HPLC columns & accessories.

Questions about UHPLC Guard Columns NUCLEODUR®, C18 PAH, 1.8µm, 4x3mm, 3 unit(s)
What is this article?
UHPLC Guard Columns NUCLEODUR®, C18 PAH, 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 Chromatographie.
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.
