Description
UHPLC Guard Columns NUCLEODUR® C18 HTec, 1,8 µm, 4 × 3 mm provide upstream protection for ultra-high-performance liquid chromatography columns. Featuring C18 HTec chemistry and 1,8 µm particles in a 4 × 3 mm format, they are intended for UHPLC reversed-phase setups that demand fine-particle performance and conventional C18 selectivity. Installed before the analytical column, the guard bed helps retain particulates and highly retained matrix components, supporting stable chromatography under elevated UHPLC pressures. The pack comprises 3 pc(s) and weighs 0,023 kg, suitable for planned exchange in busy analytical environments. Manufactured by MACHEREY-NAGEL, the NUCLEODUR® UHPLC guard line matches the stated phase and geometry for straightforward system configuration. Laboratories engaged in method transfer, QC release testing or high-throughput UHPLC can use these guards to help safeguard analytical media while keeping the separation chemistry consistent. Specification of particle size, phase and 4 × 3 mm dimensions supports accurate selection alongside compatible analytical columns and holders.
This article belongs on HPLC guard columns, in HPLC columns & accessories.

Questions about UHPLC Guard Columns NUCLEODUR®, C18 HTec, 1.8µm, 4x3mm, 3 unit(s)
What is this article?
UHPLC Guard Columns NUCLEODUR®, C18 HTec, 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.
Which category should I open next?
