Chromatography Columns and Cartridges
Waters Corp Waters Guard Column, 5 μm, 4.6 mm ID, 10 mm Length, Polymer
The Shodex KF-G Guard Column is designed to maintain analytical column performance by extending its lifespan, primarily supporting legacy methods. It removes chemical and particulate materials from the mobile phase, protecting the analytical column from harm and preventing impurities and interference in analysis. This guard column supports a broad range of applications for low to high molecular weight compounds, aiding in characterizing polymer molecular weight distribution to determine polymer physical properties.
- Not intended for improving column resolving power.
- Easy to use and attached with analytical columns.
- Offers a broad pH range from 2 to 12 and sustains a maximum pressure of 6000 psi (415 Bar).

YMC America, Inc ODS-A guard 200A 10um 20x4mm
YMC-Pack ODS-A is a high-coverage fully-endcapped C18 phase which exhibits exceptional lot-to-lot reproducibility It is available in three different pore sizes and is suitable for the separation of a wide range of compounds YMC-Pack ODS-A in 120 pore size is used for high performance reversed phase separations It has selectivity for the separation of many organic compounds found in pharmaceutical chemical and biotechnology industries 200 ODS-A offers a unique mix of moderately large pores and high surface area for the analysis of compounds ranging from small organics and pharmaceuticals to moderately-sized proteins
YMC America, Inc ODS-AQHG grd 120A 10um 30x10mm
YMC-Pack ODS-AQ is a unique reversed-phase material with both a hydrophobic high carbon loading and a relatively hydrophilic surface Because of the hydrophilic surface ODS-AQ can be wetted with polar eluents It provides chromatographers reproducible retention and excellent peak shape in highly aqueous mobile phases including 100% water This is due to the C18 ligands on ODS-AQ actually being lifted from the surface by the action of the eluents penetrating the silica pores Selectivity on YMC-Pack ODS-AQ can be subtly different from that seen on conventional ODS columns Differences in selectivity are most often encountered when analyzing mixtures of relatively polar compounds Typically longer retention and greater resolution are observed with ODS-AQ Available in both 120 and 200 pore sizes YMC-Pack ODS-AQ is well-suited for analysis and purification of peptides and other biomolecules

Waters Corp Waters VanGuard Pre-column, C8, 1.7 μm, 130 Å, 2.1 mm x 5 mm
The ACQUITY BEH C8 VanGuard Pre-column is designed to protect and extend the lifetime of UPLC and UHPLC analytical columns. It effectively removes particulate and chemical contamination while maintaining separation efficiencies, ensuring reliable and cost-effective performance in high-pressure chromatographic applications.
- Less retentive than C18 sorbent, improving peak shape and performance.
- BEH particles provide wide pH range (1 to 12), superior low pH stability, ultra-low column bleed.
- Direct connection to column inlet minimizes extra column volumes and leaks.
- For UPLC and UHPLC, sustains pressures up to 18,000 psi.
- Uses identical packing materials as analytical columns.
- Extends analytical column lifetimes by removing contamination.
- Cost-effective solution for enhancing column longevity.
- PEEK sealing surfaces ensure leak-free connections.
