3. Setup
Proper setup is crucial for optimal performance and longevity of your chromatography column. Follow these guidelines:
- Inspection: Upon receipt, carefully inspect the column for any signs of damage during shipping. Verify that the model number matches your order.
- Storage: Store the column in its original packaging at room temperature, away from direct sunlight or extreme temperatures, until ready for use. Ensure end caps are securely in place.
- System Compatibility: Ensure your HPLC system is compatible with the column dimensions (3mm ID x 150mm length) and pressure limits.
- Installation:
- Connect the column to the HPLC system using appropriate low-dead-volume fittings. Ensure connections are finger-tight, then tighten an additional quarter to half turn with a wrench to prevent leaks.
- Note the flow direction arrow on the column label and install it accordingly.
- Equilibration: Before first use, equilibrate the column with your mobile phase.
- Flush the column with at least 10-20 column volumes of the initial mobile phase at a low flow rate (e.g., 0.1-0.2 mL/min) to remove any storage solvent and stabilize the stationary phase.
- Increase the flow rate gradually to the desired operating flow rate.
- Monitor the baseline stability with your detector. Equilibration is complete when a stable baseline is achieved.
Note: Always refer to your HPLC system's manual for specific connection and operation procedures.
4. Operating Instructions
Adhere to these guidelines for effective operation of the Pro C8 column:
- Mobile Phase Preparation:
- Use high-purity solvents and reagents.
- Filter all mobile phases through a 0.2 µm or 0.45 µm membrane filter to remove particulates.
- Degas mobile phases thoroughly to prevent air bubbles in the system.
- Sample Preparation:
- Filter all samples through a 0.2 µm or 0.45 µm syringe filter to protect the column from particulate matter.
- Ensure samples are dissolved in a solvent compatible with the mobile phase to avoid precipitation upon injection.
- Flow Rate and Pressure:
- Operate within the recommended flow rate range for a 3mm ID column (typically 0.3-0.8 mL/min, depending on particle size and application).
- Monitor system pressure. Sudden increases in pressure may indicate column clogging or blockages.
- Temperature:
- Maintain a stable column temperature for reproducible results. Use a column oven if available.
- Avoid operating at excessively high temperatures, which can degrade the stationary phase.
- Shutdown:
- Before shutting down the system or storing the column, flush it with a suitable storage solvent (e.g., 100% acetonitrile or methanol) to remove salts and buffers.
- Never leave the column in an aqueous buffer solution for extended periods.
5. Maintenance
Regular maintenance extends the lifespan and ensures consistent performance of your Pro C8 column:
- Cleaning:
- If column performance degrades (e.g., peak broadening, tailing, or increased backpressure), a cleaning procedure may be necessary.
- Consult YMC America's technical support or product literature for specific cleaning protocols for C8 columns. Generally, strong organic solvents or specific wash solutions are used.
- Storage:
- For short-term storage (days to weeks), flush the column with 100% organic solvent (e.g., acetonitrile or methanol) and cap the ends securely.
- For long-term storage (months), store in 100% organic solvent, cap securely, and keep in a cool, dark place.
- Never store the column dry or in an aqueous buffer.
- Guard Columns: Consider using a compatible guard column to protect the analytical column from irreversible adsorption of sample components and particulate matter, significantly extending its lifespan.
