4.6mm Guard Column Used in HPLC Directly Rotating Head
Lab Liquid Chromatography Column Hardware Filters
Changing HPLC column frit can withstand pressure up to 600.
uHPLCs® columns feature innovative particle technology:
*Enables faster and more efficient HPLC separations.
Material options for HPLC frit:
* PEEK Circle
* Stainless steel sintered metal
Selection criteria for HPLC column frits:
* 0.5 μm pore size frit is used to retain packing prepared from 3 μm particles.
* 2 μm pore size frit is used to retain larger particles.
* Ultrasonically cleanable.
* Requires special tools for mounting on both ends of the column.
Features and Applications:
uHPLCs’ Peek HPLC Frits Manufacturing Details:
- We produce HPLC frits from chromatographic-grade 316 stainless steel.
- We provide a variety of sizes to accommodate diverse column and pore sizes.
- Our frits serve the dual purpose:
- Protection of HPLC columns against particulate contamination.
- Uniform distribution of dissolved samples, ensuring optimal column performance.
Choosing the Right Frit:
- Ensure the frit’s pore size is compatible with the particle size of the column packing.
- If the packing particle size is smaller than the frit’s pore size, there’s a risk of the frit getting clogged by the packing.
Replacement Frit Options:
- Available in both PTFE and PE.
- Come in a range of pore sizes to suit specific requirements.
- When selecting a frit, it’s essential to match the column’s inner diameter (ID) for a precise fit.
- Retain column packing effectively.
- Ensure uniform distribution of the sample into the column.
- Facilitate consistent sample flow into the column.
- Meet specific customer flow dimension requirements.
- Must be resilient, enduring pressures exceeding 6000 psi and highly corrosive conditions.
- Minimize dead volume to enhance peak symmetry.
