Installing the uHPLCs Guard Protection System is seamless and efficient:
We can customize the design and specification of guard columns based on the specific requirements of the OEM.
We offer private labeling solutions for OEM guard columns, which includes the OEM's branding, logo, and labeling.
We review every aspect of the production process for excellence and consistently deliver exceptional results.
We provide technical support for OEM guard columns with expert assistance on troubleshooting, maintenance, and training.
uHPLCs manufactures high-quality HPLC guard columns designed to protect analytical and semi-preparative columns.
1. Our columns have properties like low dead volume, high peak capacity, and excellent retention stability. With their expertise in analytical chemistry and commitment to innovation and customer satisfaction, uHPLCs has become one of the leading HPLC guard column manufacturers.
2. Achieve Better Chromatographic Separation, accuracy, and reproducibility in your analyses with uHPLCs guard columns.
A HPLC guard column traps particulates, sample impurities, matrix residues, and strongly retained compounds before they reach the analytical column. This prevents contamination, pressure increases, and peak shape deterioration — which helps extend column lifetime.
No — our guard columns are designed with low dead volume to maintain stable peak shape and consistent chromatographic performance. If properly matched to your analytical column, there is no negative impact on resolution.
Match these parameters to your analytical column:
Same stationary phase (e.g., C18 / C8 / CN / Phenyl)
Same or smaller particle size (3 μm / 5 μm)
Same column ID (2.1 / 3.0 / 4.0 / 4.6 mm)
If you’re unsure, send us your main column model and we will recommend the correct guard column.
Yes — our guard columns are compatible with Agilent, Waters, Thermo, Shimadzu, and most standard HPLC fittings. Custom adapters are available if needed.
Lifetime depends on sample cleanliness and application, but customers typically see a 3–10x longer analytical column life. When backpressure rises or peak shape degrades, the guard cartridge should be replaced.
You can replace only the guard cartridge — the holder can be reused many times. This keeps long-term consumable cost very low.
Yes — we support OEM/ODM for:
✔ Special lengths / IDs
✔ Custom stationary phases
✔ High-temperature or corrosive media applications
Yes — UHPLC cartridges with smaller particle sizes are available. Just specify your main column model or application.
Standard sizes are in stock for fast delivery. Customized specifications can be produced upon request.
