<p>An apparatus and method for verifying the drop delay in a flow cytometer (100), which is indicative of the time that elapses from a moment at which a particle of interest is detected at an interrogation point (122) in the flow of cytometer to the moment at which a sorting condition, such as a charging potential, is applied in response to the detection to a droplet forming at a droplet forming location (122) in the flow cytometer. The apparatus and method analyzes the content of the droplets at the droplet formation point (112) or at a location downstream of the droplet formation point, to detect the presence or absence of a particle of interest that was detected at the interrogation point (122) in the flow cytometer. The drop delay time at which the droplets being formed by the flow cytometer are charged can then be set based on the results of the analysis of the content of the droplets, to ensure that droplets containing particles of interest are charged and thus sorted by the flow cytometer, while droplets not including particles of interest remain uncharged and are not sorted.</p> |
