The leec biochip can be connected with pcb ( printed circuit board ) , thus it can generate a moving electric field by changing time , scope and field intensity discretionarily under single chip processor ' s control . meanwhile it is probable to reduce driving voltage and decrease temperature greatly , and so increase resolution of dna separation 研究内容包括线性分布式电极阵列的理论设计，以普通载波片和有机高聚物pdms ( polydimethylsiloxane )为基本材料的芯片制作工艺， leec芯片和pcb板的连接方式，硬件控制系统的设计以及控制芯片工作的单片机程序编制等，此外还包括电化学检测方法的研究。
Ultraviolet absorption detector , photodiode array detector ( dad ) , fluorescence detector , and electrochemical detector are optional detectors , response value of which is relative to not only quality of the object under test , but also structure of the compound ; refractive index detector and evaporative light - scattering detector are universal detector , responding to structure of all compounds ; evaporative light - scattering detector is quality - type detector , whose responding value only relates to quality of the object under test for compounds with similiar structures ; photodiode array detector ( dad ) can , at the same time , record absorption spectra of the object under test in a prescribed wave scope , consequently , it can be used in spectrum control and inspection of purity of chromatographic peaks of the object under test 紫外、二极管阵列、荧光、电化学检测器为选择性检测器，其响应值不仅与待测物的质量有关，还与化合物的结构有关；示差折光检测器和蒸发光散射检测器为通用型检测器，对所有的化合物结构均有响应；蒸发光散射检测器属质量型检测器，对结构类似的化合物，其响应值几乎仅与待测物的质量有关；二极管阵列检测器可以同时记录待测物在规定波长范围内的吸收光谱，故可用于待测物的光谱管制和色谱峰纯度的检查。
