Avio 220 Max 混合直读 ICP-OES配备独特的衰减模式,可以选择性地减少分析物的信号,实现对较高浓度分析物的测量,从而扩展了ICP-OES的动态范围,并且不会影响其对低浓度分析物的测量能力。衰减模式为使用者提供了诸多优异的性能体验,如简化的方法、最小的样品稀释度以及无需使用次灵敏波长即可测量更高浓度的能力。
True phase-matched second-harmonic generation in a waveguide of crosslinkable ferroelectric liquid crystals is demonstrated. These materials allow the formation of macroscopically polarstructures whose order can be frozen by photopolymerization. Homeotropic alignment was chosen which offers decisive advantages compared to other geometries. All parameters contributing to theconversion efficiency are maximized by deliberately controlling the supramolecular arrangement.The system has the potential to achieve practical level of performances as a frequency doubler for low power laser-diodes.
