Radiometer ABL 90 Cord Blood Specimens

I would like some feedback if you:

Perform Cord bloods on the ABL 90? Volume per month? Is the cord blood collected from the cord or from a vessel art line/venous line. Do the cord blood specimens impede the flow path on the ABL 90?  If you don't use the ABL 90, do you use a ABL 825 or some other method such a EPOC or ISTAT.
