        vacancy chromatography     This LC technique utilizes an indirect
        detection method for quantitation.

        vacuum manifold An apparatus that is used in conjunction with
        the simultaneous processing of multiple SPE samples.

        validation The process of statistically determining that the results
        obtained by conducting a defined test protocol meet predetermined
        accuracy, precision, linearity, repeatability, recovery, robustness, and
        ruggedness values.

        van Deemter equation A mathematical equation defining the
        relationship between the plate height, H, in a column and the linear
        velocity of the mobile phase through the column, u:


























        This diagram shows the individual contributions (various dashed lines) to the plate
        height in the van Deemter equation. The total H is shown by the solid curve.
