1)
Large amounts of droplets were full of detection area caused by high flow rate and led to droplet size increasing in
5 seconds. Data was therefore collected in 4 seconds.
2)
The sample contained too many droplets sample input. We therefore collected data using 4/5 of the original
droplet amount.
