NOTE

The pressure drops in table 13 are calculated for water (viscosity 1) and for a flow rate of

10 µl/min.

NOTE

The pressure drops in tables 7 to 13 are indicated values at a specific flow rate and with

water (viscosity = 1). For other solvents or other flow rates, use the indicated relation to

calculate the approximate pressure drop. Depending on tolerance of the capillary diameter

the pressure drop values can vary by +/- 25% compared to the calculated results.
