Beschreibung
HPLC Guard Columns NUCLEODUR® 100-5 NH2 are compact protective pre-columns for high-performance liquid chromatography. Each unit measures 4x3 mm and uses the NUCLEODUR® 100-5 NH2 stationary phase, helping retain particulates and strongly retained matrix components before they reach the analytical column. This approach supports longer column lifetime, more stable backpressure, and more consistent peak shape in routine and method-development work. The pack contains 3 pc(s) and is offered from manufacturer MACHEREY-NAGEL for laboratories that need reliable amino-phase guard protection without changing established HPLC parameters. The small 4x3 mm format is intended for use with compatible guard-column holders in standard HPLC systems. Amino-bonded NUCLEODUR® selectivity is relevant for polar and hydrophilic analytes under normal-phase or HILIC-type conditions, depending on the mobile phase and method design. These guard columns suit analytical chemistry, quality-control, and research environments where reproducible chromatography and controlled consumable costs are important. Integrating a dedicated guard column upstream of the main column is a practical step to reduce contamination risk and protect high-value analytical packing during sample sequences.
