In HPLC columns, reverse-phase and normal-phase chromatography separation methods are based on polarity. Reverse phase columns separate analytes based on their hydrophobicity, with the more hydrophobic compounds being retained longer on the column. Separations based on charge utilize ion-exchange chromatography.

Top 7 Questions You Should Ask When Buying HPLC Columns:

1. Based on your analyte(s), matrix, separation goals, and instrumentation, what column does the vendor recommend?

2. What benefits does this column offer over your current column? Performance? Lifetime? Reproducibility? Etc.

3. How should you clean/prepare your sample prior to injection on the column?

4. How do you care for the column? Conditioning, cleaning, storage, etc.

5. What type of chromatographic media (fully porous, monolithic, core-shell) is going to provide the most benefit for your separation?

6. Do you need a unique selectivity (HILIC, polar-end capped, etc.) to separate any very polar and/ or non-polar components in your mixture?

7. What column dimension is going to be most suitable for your loading requirement?
