摘要
作者介绍作者最新研制出来的ＢＹ－Ⅰ型微量元素分析仪的工作原理、特点以及仪器硬、软件结构及功能。该分析仪能测定出含量仅为十亿分之几的多种微量元素，其相对误差为３％～１０％，变异系数小于１０％，而价格却只有原子吸收光谱仪等大型精密仪器的十几分之一，具有很大的实用意义。可广泛应用于医学及环保等领域。
The principle,feature of recently developed Model BY-Ⅰ microelements analysis instrument are introduced,and its hardware, software,and functions as well. The instrumentcan measure several one-billionth of trace elements.The relative error is 3～10%.The diversity is less than 10%. The price of this instrument is only several one-tenth of that of those large precision instrument,such as atom absorb spectrum.It has great practical meaning and can be widely used in the field of medicine,environmental protection,etc.
