The MS hyphenation performance of UniSpray®, a new design of atmospheric pressure ionization source was evaluated in both SFC and RPLC modes. Sensitivity, stability, versatility and matrix effects offered by the UniSpray were assessed in positive and negative ionization modes and systematically compared to an electrospray source (ESI) using 120 natural compounds covering an extended chemical space. In a first instance, a multivariate approach was used to screen and optimize the UniSpray source settings to maximize detection sensitivity.
