4.6mm Guard Column Used in HPLC Directly Rotating Head
* uHPLCs guard column assembly consists of a guard holder and guard cartridge.
* It combines stainless steel’s strength with the convenience and efficiency of a PEEK guard cartridge.
* A small section of the same packing as the column is inserted between the injection valve and the column.
* No tools are required for the insertion process.
* The guard column assembly will extend the column’s life and ensure reproducible results.
Features and Applications:
Direct Connect 4.6mm HPLC Guard Column Features:
- Protective Function: Installed between the injector and the analytical column, it acts as a pre-trap for substances that can strongly adsorb to the analytical HPLC column and are not easily washed away by the mobile phase.
- Extended Column Life: Effectively protects and prolongs the lifespan of the analytical HPLC column.
- Length Options: Available in 1 cm (10 mm), 2 cm, and 3 cm lengths. Longer guard columns offer increased chromatographic packing and enhanced protection performance.
- Sample Flexibility: Suitable for various liquid chromatographic analytical work, with the option to select the appropriate guard column length based on sample cleanliness and replacement frequency.
- Inner Diameter: Typically matches the inner diameter of the analytical liquid chromatographic column for seamless integration.
- Cartridge Compatibility: Accepts cartridges with inner diameters of 4.6mm, 3.0mm, or 10mm, and lengths of 4mm, 10mm, or 12mm.
- Comprehensive Selection: Offers a wide range of stationary phase chemistries from UHPLCS, ensuring compatibility between the guard column and the analytical column.
- Tool-Free Assembly: Easy cartridge replacement without the need for additional tools, simplifying maintenance procedures.
The direct connection guard column: Direct connection design, without any additional connection cable
– Quick and easy hand-tight installation
– Easy replacement of the guard column cartridge
