Optimized for Challenging SeparationsAchieve superior resolution and sensitivity for structurally related aromatic and polar compounds with the ULTRA Cartridges UHPLC Biphenyl Column. Advanced biphenyl chemistry promotes strong - interactions and robust analytical reproducibility.
Reliable Performance and CompatibilityBuilt for demanding UHPLC environments, these columns withstand high operating pressures (up to 1200 bar) and temperatures (up to 80C). The stainless steel hardware and UHPLC-compatible compression end-fittings ensure reliable installation across most major instrument brands.
Ready-to-Use and Easy to StoreEach cartridge is pre-packed, eliminating preparation steps and speeding up installation. For optimal longevity, store the columns in acetonitrile or a compatible solvent when not in active use.
FAQs of ULTRA Cartridges UHPLC Biphenyl 4.6mm ID Columns:
Q: How do I install the ULTRA Cartridges UHPLC Biphenyl Column in my UHPLC system?
A: The column features UHPLC-compatible compression end-fittings and standard UHPLC connection ports, making it quick and easy to integrate into most instrument brands. Simply secure the ends and follow your systems installation protocol.
Q: What types of analytes are best separated using this biphenyl UHPLC column?
A: This column is particularly suited for the separation of aromatic and polar compounds, thanks to its biphenyl bonded silica, which enhances - interactions and facilitates improved separation of structurally related analytes.
Q: What is the recommended flow rate for optimal performance?
A: For the 4.6 mm ID column, a flow rate between 0.53.0 mL/min is recommended. Adjust the rate according to the column size, particle size, and the specific requirements of your analysis.
Q: Where should I store the column when not in use?
A: To preserve the columns performance and longevity, store it in acetonitrile or an appropriate solvent, as specified in the product instructions. Avoid prolonged dry storage or exposure to incompatible solvents.
Q: When is it necessary to replace the column?
A: Replace the column when you observe persistent loss of resolution, increased backpressure, or when baseline noise interferes with reliable analysis despite maintenance and cleaning.
Q: What are the primary benefits of the biphenyl chemistry in this column?
A: The biphenyl bonded phase promotes enhanced separation of aromatic and structurally related compounds, offering high resolution and increased selectivity, which is beneficial for complex samples and method development.
Q: Can I use this column with high pH mobile phases?
A: ULTRA Cartridges UHPLC Biphenyl Columns are compatible with a pH range of 2.08.0. It is not recommended to use mobile phases with pH outside this range to protect column integrity and stability.
