The Metrosep A Supp 5 Guard/4.0 reliably protects the Metrosep A Supp 5 and 7 IC anion columns against contamination from the sample or the eluent.
Enhance Analytical Column LongevityDesigned for inline use with Metrosep A Supp 5 analytical columns, the Guard/4.0 effectively shields your main column from harmful contaminants. By capturing particulates and chemical impurities, it minimizes wear, helping laboratories achieve consistent, reliable results over extended analytical runs.
Precision Engineering for Reliable PerformanceWith a stainless steel body and a carefully engineered 5 m particle packing, this guard column delivers optimal flow, pressure stability, and superior resistance to diverse sample matrices. Its robust construction ensures suitability for rigorous routine use in professional analytical environments.
FAQs of Metrohm Metrosep A Supp 5 Guard/4.0:
Q: How does the Metrosep A Supp 5 Guard/4.0 protect analytical columns?
A: The guard column is installed inline before the main column to trap particulate and chemical contaminants. This prevents fouling of the analytical column, significantly extending its usable lifespan and maintaining performance consistency during ion chromatography.
Q: What is the recommended process for installing the Metrohm Metrosep A Supp 5 Guard/4.0?
A: To install, securely connect the guard column to your Metrosep A Supp 5 analytical column using the standard Metrohm column fittings. Ensure all connections are properly tightened and that the guard is oriented in the correct flow direction as per the instrument manual.
Q: When should I replace the guard column?
A: Guard columns should be replaced when you notice increased backpressure, declining separation efficiency, or after a specified number of injections as recommended by your laboratorys maintenance procedures. Regular replacement helps maintain optimal chromatographic performance.
Q: Where can the Metrosep A Supp 5 Guard/4.0 be used?
A: This guard column is ideal for use in analytical laboratories, especially those specializing in ion chromatography for anion separation. Its robust construction is suitable for academic, industrial, and research laboratory settings.
Q: What are the benefits of using a guard column with the Metrosep A Supp 5 analytical column?
A: Using a guard column helps prolong the life of the main analytical column, reduces maintenance costs, and supports consistent chromatographic results by preventing contamination and clogging. It is a cost-effective solution for improving overall system reliability.
Q: How does pH stability and maximum pressure capacity of the guard column impact its usage?
A: The pH stability range of 212 and its ability to handle pressures over 30 MPa (300 bar) ensure compatibility with a wide range of anion analysis applications and high-pressure chromatographic methods, making it versatile for demanding workflows.
