能够在真空中运行的超薄平坦液体片的发展为液相和溶液相的X射线吸收光谱提供了令人兴奋的新目标。已经有几种方法可用于使用不同的喷嘴设计来输送真空中的片材射流。我们比较了由两种不同类型的喷嘴生产的片材;市售的硼硅玻璃芯片使用微流体通道来输送碰撞射流,以及内部制造的扇形喷嘴,其将轴上的液体从缝隙中压缩出来以实现碰撞条件。我们发现,在我们的测试中,这两个喷嘴都适用于X射线吸收光谱与风扇喷嘴产生更厚,但更稳定的射流比商业喷嘴。我们还提供了如何在真空中运行这些喷嘴的实用细节。
The development of ultra-thin flat liquid sheets capable of running in vacuum has provided an exciting new target for X-ray absorption spectroscopy in the liquid and solution phases. Several methods have become available for delivering in-vacuum sheet jets using different nozzle designs. We compare the sheets produced by two different types of nozzle; a commercially available borosillicate glass chip using microfluidic channels to deliver colliding jets, and an in-house fabricated fan spray nozzle which compresses the liquid on an axis out of a slit to achieve collision conditions. We find in our tests that both nozzles are suitable for use in X-ray absorption spectroscopy with the fan spray nozzle producing thicker but more stable jets than the commercial nozzle. We also provide practical details of how to run these nozzles in vacuum.
