用火焰原子吸收光谱法测定微量标本中的微量金属元素 ,如分析血液微量金属元素 ,在卫生检验中有重要意义。这种方法无须改动仪器 ,只要用微量注射器将血样加在预先用钻头钻好的聚四氟乙烯棒端上的浅洞内 ,将塑料毛细管插进吸入火焰中便可完成一次脉冲喷雾测定 ,该方法也称为“ Determination of trace metal elements in trace samples by flame atomic absorption spectrometry, such as the analysis of blood trace metal elements, is of great significance in the hygienic test. This method without changing the instrument, as long as the micro-syringe with a blood sample pre-drilled with a Teflon rod on the shallow hole, the plastic capillary tube inserted into the inhalation flames can be completed a pulse spray measurement, the The method is also called "
