The new Micro- and Nanofocus small- and wide angle X-ray Scattering undulator beamline (MiNaXS) P03 at the high-brilliance third-generation synchrotron radiation source PETRA III combines in a unique way low divergence and a microfocus and additionally a nanofocus beam. Being commissioned in 2010, the microfocus end station is operational. Using a microfocus beam size of 22x12µm2, a SAXS resolution of >100nm has already been achieved. We prove its versatility by combining in-situ the microfocus with grazing incidence SAXS (GISAXS) and imaging ellipsometry [1]. We present first results on in-situ experiments, utilizing the high time- and spatial resolution for drop-casting experiments, and give an outlook on the novel possibilities for investigating in real time structure formation upto mesoscopic length scales.
