An Optical Approach for the Determination of Droplet Volumes in Nanodispensing

Table 4

Estimate of the difference in volume if the edge is incorrectly detected.

Drop volume	Diameter (rounded)	Difference in volume with 𝑎−1 diameter	Difference in volume with 𝑎+1 diameter
100 pl	37 pixels	7.9%	8.3%
150 pl	43 pixels	6.8%	7.1%
200 pl	47 pixels	6.2%	6.5%
250 pl	50 pixels	5.9%	6.1%
300 pl	54 pixels	5.5%	5.7%
350 pl	56 pixels	5.3%	5.5%
400 pl	59 pixels	5.0%	5.2%
450 pl	61 pixels	4.8%	5.0%
500 pl	64 pixels	4.6%	4.8%
