13. ABSTRACT (cont'd)
We were unable to detect (using HPLC analyses and a UV detector) any constituents leaching
from any of the tubings used in these studies, even when a slow flow rate was used. However,
desorption of sorbed analytes is a concern for all the tubings tested, including the rigid fluoropoly-
mer.
