Description
EC 4/3 NUCLEOSIL 100-3 C18 NAUTILUS is an HPLC guard column (pre-column) that shields analytical HPLC columns from particulates and matrix contaminants. The cartridge measures 4 mm in length with a 3 mm internal diameter and is filled with the NUCLEOSIL 100-3 C18 NAUTILUS phase. It is intended for main columns with 3, 4 or 4,6 mm internal diameter and must be mounted in the Column Protection System guard-column holder (REF 718966). Delivered as a pack of three pieces from manufacturer Macherey-Nagel, these EC cartridges help prolong analytical-column lifetime, maintain retention stability and support consistent peak performance in routine HPLC. The C18 NAUTILUS chemistry is suited to reversed-phase separations where polar and non-polar interactions are balanced. Using a matching guard format preserves the selectivity of the main NUCLEOSIL 100-3 C18 NAUTILUS column while offering a practical, cost-effective protection step for method development, QC and everyday laboratory chromatography.
This article is part of HPLC columns, in HPLC columns & accessories.

Questions about EC 4/3 NUCLEOSIL 100-3 C18 NAUTILUS
What is this article?
EC 4/3 NUCLEOSIL 100-3 C18 NAUTILUS 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.
Which category should I open next?
