【摘要】：高黏度液体的pL级微量分配和狭小空间内的点样是微量液体分配的难点,针对这个问题,文中从机理上分析了影响转印式pL级点样性能的因素,通过实验研究了液体黏度、移液针的移动速度、停留时间、液窝对点样性能的影响,实现了高黏度(5、30Pa·s)的pL级液体分配和窄缝内(0.5mm×20mm)的微量点样.研究结果表明:低速点样时,液体分配量随着液体黏度的增加呈增加趋势,且受移液针停留时间的影响较小;高速点样时,液体黏度对液体分配量的影响较小,但移液针的停留时间对点样量有较大的影响;通过合理匹配参数,转印式液滴分配方法可以有效地抑制液窝的生成,减小随机因素的影响,实现高黏度液体的高准确性、高一致性pL级超微量点样和狭小空间内的封装点样.
[Abstract]:The pL level distribution of the high viscosity liquid and the point in the narrow space are the difficulties of the micro liquid distribution. In this paper, the factors affecting the performance of the transfer type pL grade are analyzed in this paper. The influence of the viscosity of the liquid, the moving speed of the needle, the stopping time and the performance of the liquid nest are studied through the experiment, and the high viscosity is realized. The pL level liquid distribution of the degree (5,30Pa. S) and the micro point sample in the narrow seam (0.5mm x 20mm). The results show that the liquid distribution increases with the increase of the viscosity of the liquid, and is less influenced by the retention time of the liquid. Through reasonable matching parameters, the transfer method can effectively suppress the formation of the liquid nest, reduce the influence of random factors, realize high accuracy of high viscosity liquid, high consistency pL super micro point sample and the sealing sample in narrow space.
