Are You in the Market for... Chromatography Columns?

Find out the most common phases used and more in our latest survey results.

The wide spectrum of columns available makes selecting this most important component of an LC system extremely difficult. Column choices span normal phase, reverse phase, size exclusion, ion exchange, hydrophobic interaction, and affinity chromatography. One is hard-pressed to find a more innovative, self-reflective instrument market.

Top 7 Questions You Should Ask When Buying a Chromatography 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 nonpolar components in your mixture?
  7. What column dimension is going to be most suitable for your loading requirement?
