摘要

本文提出了一种用于非接触式监测微液滴的传感器。在我们之前的工作[1]的基础上，该传感器现在允许在20至100 nl的体积范围内对单个液滴进行直接定量体积测定。改进的电子传感器能够以ΔV±3nl的精度测量液滴体积。传感器信号提供有关被监测液滴的各种信息，例如液滴速度。本文特别考虑了液滴速度对体积测量的影响。结果表明，如果正确地解释信号，速度效应可以完全补偿。

Quantitative volume determination of dispensed nanoliter droplets on the fly

In this paper we present a sensor for non-contact monitoring of dispensed micro-droplets on the fly. In extension to our previous work [1], the sensor now allows for a direct, quantitative volume determination of single liquid droplets in the volume range from 20 to 100 nl. The improved electronic transducer enables to measure the droplet volume with an accuracy of ΔV ± 3 nl. The sensor signal provides a variety of information about the monitored droplet like for examples droplet velocity. This paper considers in particular the influence of the droplet velocity on the volume measurement. It turned out that the velocity effect can be fully compensated, if the signals are interpreted correctly.
