What is a Void Volume? Definition from Corrosionpedia

Jun 04, 2014· Void volume is the volume of mobile phase (V m or V 0) in a column. In an ideal case, it is equal to the mobile phase hold-up volume. For example, if the stationary phase occupies 40% of the total column volume, the void volume would be 60% of the total column volume. Consider a column that is 25 cm long with an inner diameter of 1 cm.

HPLC Column Void Volume : Pharmaceutical Guidelines

The HPLC column void volume denoted V m o r V 0 is in simple terms the volume of the mobile phase in the column. It is the part of a fraction that when added to the volume of the stationary phase makes up a whole fraction or 100% volume. The HPLC column void volume is considered in the presence of the stationary phase particles, meaning that if

What is void volume in SEC? Phenomenex

Apr 13, 2016· The void volume corresponds to the amount of mobile phase in an LC system. In most separation modes the void volume would be equivalent to the amount of mobile phase needed to elute a compound that doesn’t interact with the stationary phase and is hence unretained.

How do I determine the void volume in HPLC?

The void volume of a system is usually determined by injecting an unretained standard (Uracil in RP-HPLC) that has no or very little retention on a particular phase. Slight variations in this value are explained by the extra column dead volume of your specific system configuration and set-up.
