1. A system for performing a photopheresis procedure comprising:
a) a separator for separating a target cell population from blood, said separator comprising a separation device configured to receive a separation chamber;
b) an illumination device for treating said target cell population with light, said illumination device comprising an irradiation chamber wherein said irradiation chamber is configured to receive a treatment container;
c) a fluid circuit mounted on the separator, said fluid circuit including said treatment container, said treatment container integrally connected to one or more sample pouches, wherein the one or more sample pouches comprises a first sample pouch for collecting a sample prior to addition of a photoactivating agent, a second sample pouch for collecting a sample after addition of said photoactivating agent but prior to irradiation, and a third sample pouch for collecting a sample after irradiation; and
d) a controller coupled to the separator and illumination device, wherein the controller is configured to pause said photopheresis procedure and allow for the collection of a sample of said target cell population in one or more of said first, second and third sample pouches respectively at one or more of (1) prior to addition of the photoactivating agent to said target cell population, (2) after addition of said photoactivating agent to but prior to irradiation of said target cell population and (3) after irradiation of said target cell population.
