FIG. 1.

Liquid flatjet system used for solution phase soft-x-ray absorption spectroscopy, consisting of an HPLC pump, directing the liquid solution from a reservoir to two nozzles placed in a vacuum chamber, resulting in two single laminar jets with 50 μm thickness obliquely colliding under an angle of 2α = 48°. The colliding jet geometry is shown from two orthogonal directions, showing the formation of two flatjet sheets with planes orthogonal to each other. The scaling is in mm units. The liquid jet is then directed to a catcher unit and recycled back to a solution reservoir. The vacuum chamber used in the UE52-SGM beamline, equipped with differential pumping,³⁴ is depicted underneath. For further details, see the text.
