Abstract

The association by aligned direct bonding of an evanescent wave optical sensor and small-volume flow cells for visible absorption detection is demonstrated. We show that for sample volumes ranging from 760 to 190 nl and a sensor interaction length of 1 mm, very small cross-sectional dimensions of fluid channels are no more a serious obstacle for optical detection. The lowest limit for the channel depth is the penetration depth of the
