把流动注射技术和试制的流通pNa电极联用来测定电子级纯水中的痕量钠,检测下限可达0.1ppb。本方法快速、灵敏。准确而又方便。是目前已知的测量痕量钠的最好方法之一。特别适用于半导体工业和大规模集成电路制备工艺用水中对钠的检测。
The flow injection technology and trial circulation of pNa electrode used in conjunction to determine trace levels of sodium in pure water, the detection limit of up to 0.1ppb. This method is fast and sensitive. Accurate and convenient. It is one of the best methods of measuring trace sodium so far known. Particularly suitable for semiconductor industry and large scale integrated circuit manufacturing process of sodium in water testing.
