Top 5 Signs That You Should Service or Replace Your HPLC Columns

article image The backpressure increases above the column or system limit. A common practical limit is a 10-20% increase.
article image A quantitative chromatographic system suitability parameter fails: resolution, tailing factor, S/N, RRT, efficiency.

A qualitative chromatographic parameter changes significantly from the expected: Peak shape, background response, irregular baseline disturbances, column leaking.

article image Visible external hardware wear and tear: inlet/outlet threading wear, corrosion, reagent precipitates (buffer salts or derivatizing agents).
article image Known exposure to components that could afflict future selectivity under new conditions: ion-pairing agents, sample contaminants (such as inorganic ions or phospholipids), phthalates, immiscible solvents.

Top 7 Questions That You Should Ask When Buying HPLC Columns

article image Based on your analyte(s), matrix, separation goals, and instrumentation, what column does the vendor recommend?
article image What benefits does this column offer over your current column? Performance? Lifetime? Reproducibility? Etc.
article image How should you clean/prepare your sample prior to injection on the column?
article image How do you care for the column? Conditioning, cleaning, storage, etc.
article image What type of chromatographic media (fully porous, monolithic, core-shell) is going to provide the most benefit for your separation?
article image Do you need a unique selectivity (HILIC, polar-end capped, etc.) to separate any very polar and/or non-polar components in your mixture?
article image What column dimension is going to be most suitable for your loading requirement?
