How Do the Terms Nano Capillary and Micro LC Differ in Terms of Column ID and Typical Flow Rates - HPLC Primer
The following table shows the flow rate and column ID ranges for the various terms which is generally accepted by chromatographers but definitions may differ from different sources.
| Term | Colum i.d. range (um) | Flow rate range (uL/min) |
|---|---|---|
| Nano | 25–150 | 0.02–1 |
| Capillary | 150–500 | 1–10 |
| Micro | 500–1000 | 10–50 |
