Abstract
A method for detecting a separation gas in a fluid flow stream is provided herein. In one example, a voltage output signal is generated by a scatter detector of a flow cytometer as a flow stream of a plurality of gas-separated samples passes through the flow cytometer. The voltage output signal is sampled, and a timestamp and a voltage value are recorded for each sampled voltage of the voltage output signal that is greater than a separation gap threshold. In some examples the separation gap threshold is at least two times greater than a maximum voltage output of the samples. Flow cytometry systems including software configured to perform these method steps are also described.
