Determining the residence time of a massless particle in microfluidic channel

Hi all!
I have a question regarding determination of a residence time for a masless particle in microfluidic channel.
I have modeled steady fluid flow with 'Laminar Flow' physics in Comsol 4.2 through some channel geometry and now i would like to make an investigation on how long does a particle (masless or with really small dimensions) flow through the geometry. Thus measuring residence time for a particle.
Can anybody help me with this - maybe guide me to a tutorial on this subject?
Every help would be very much appreciated!
Thanks in advance and best regards,
Izidor

Dear Cosmol experts,
I managed to execute the particle tracing, so one part of my work is done.
I'd like to ask you how could I compute/determine the particle residence time. I'm simulating a rectangular channel with different structures on the bottom, thus, some of the particles get trapped by the structures and need more time to flow through the whole channel geometry.
I'd like to determine a residence time for a particle which starts from a specific point in the inlet.
Could anybody help me how to solve this? Maybe indicate a way this could be done?
Thank you very much in advance!
