摘要： A method for separating motile organisms from other organisms. The method comprises controlling a fluid delivery unit to provide a fluid flow to a sample separating device (302). The fluid flow has a sample introduction flow velocity set so that a sample may be introduced into a sample introduction zone of the device. The sample introduction flow velocity is sufficiently high such that an organism in the sample is unable to exit the sample introduction zone. The method comprises controlling the fluid delivery unit to reduce the fluid flow velocity from the sample introduction flow velocity to an operational flow velocity lower than the sample introduction flow velocity (303). The operational flow velocity is selected such that motile organisms in the sample are able to swim against the fluid flow and enter a sample collection zone of the device.
