Description
EC 4/3 NUCLEOSIL 100-5 PROTECT I is an HPLC guard column intended to shield analytical main columns from contamination in liquid chromatography systems. The cartridge has a length of 4 mm and an internal diameter of 3 mm, and is filled with NUCLEOSIL 100-5 PROTECT I stationary phase for protective use ahead of the primary separation bed. Offered as a pack of 3 pieces from manufacturer Macherey-Nagel, these EC 4/3 units match main columns with 3, 4 or 4,6 mm internal diameter. Mounting requires the Column Protection System guard column holder (REF 718966), which must be ordered separately. By retaining particulates and highly retained sample constituents before they enter the analytical column, the guard cartridge supports consistent chromatographic performance and extends usable column life. The compact EC design fits common HPLC configurations in research, industrial and quality-control laboratories that apply NUCLEOSIL PROTECT I chemistry for routine column protection.

Questions about EC 4/3 NUCLEOSIL 100-5 PROTECT I
What is this article?
EC 4/3 NUCLEOSIL 100-5 PROTECT I 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?
