Description
CPS guard column holder is a Column Protection System accessory designed for EC 4 x 2 mm and EC 4 x 3 mm guard columns in HPLC applications. The complete set comprises one guard column holder, two replacement capillaries with an internal diameter of 0,12 mm, three ferrules for HPLC columns with particle size greater than 2 µm, three ferrules for columns with particle size below 2 µm, two open-end wrenches (SW 12 and SW 14), and one instruction manual. This modular assembly helps laboratories protect analytical columns from particulates and sample matrix components while maintaining reliable, low-dead-volume connections. Supplied as a ready-to-use set from manufacturer Macherey-Nagel, the holder integrates smoothly into routine chromatographic workflows where guard cartridges are used to extend analytical column lifetime. The dual ferrule assortment accommodates both conventional and sub-2 µm packing materials, supporting method flexibility across particle-size ranges. Capillaries and tools included in the package simplify installation and everyday cartridge exchange at the laboratory bench, reducing downtime during maintenance.

Questions about CPS Guard Column Holder
What is this article?
CPS Guard Column Holder 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?
The category is HPLC columns & accessories. The sub-category is HPLC guard columns. The catalogue is Chromatography equipment.
