Stylus-based surface profiling is a standard technique for accurate, repeatable surface shape, topography and step height measurement in applications ranging from semiconductor R&D to solar cell QC.

YSI 防玷污的10点技巧 随着电子技术的进步、电源管理的改进和电池寿命的延长，生物玷污成为目前决定监测仪器投放周期长度的决定因素，特别是应用于长期、连续监测。应用一些防玷污技术可以延长仪器的维护间隔，能够减少野外的仪器维护的次数，并提高水质监测数据精度。 防玷污技巧的详细内容请参考文章《YSI 防玷污的10点技巧》

TOC与COD的测定方法不同。测定COD是采用强氧化剂和加热回流的方法，只能将水中的有机物部分氧化（氧化率较低），并且测定时间较长，即使目前一些快速的

Using Bruker’s Hysitron PI 88 SEM PicoIndenter equipped with tilt and rotation stages in conjunction with the QUANTAX EBSD system enables a more robust characterization of metallic materials by combining high resolution phase and grain orientation mapping capabilities with targeted nanomechanical property measurements. This combination could also be used to extend the scope of research related to other advanced textured, anisotropic, or multi-phase materials.
