微量移液器是用来量取0.1µl~10ml液体体积的精密仪器，是生物、化学和临床实验等分析过程中样本采集和移取的必备工具。
方法：使用微量移液器定量加液代替毛细管滴加药液。
Methods: Using micropipettor instead of capillary in adding liquid.
结果：微量移液器加液法测得结果的可信限率明显低于毛细滴管加液法。
Results:The confidence-limit rate in micropipettor is obviously lower than that of capillary.
用微量移液器加入待测溶液和硼氢化钾溶液，在反应杯中发生氢化物并导入石英管进行原子化。
Sample and KBH_4 solutions are introduced into the reaction cup with micro pipettes sequentially, then hydride generated is guide into quartz cell for atomization.
