Applications of Bipolar Pulse Conductance to Flowing Streams (Enzymes, Hplc, Immobilized, Fia)
The use of flowing streams, particularly flow injection analysis (FIA), to facilitate analytical measurements has increased significantly in the past several years. Conductance has generally not been used as a detector for flowing streams. Two reasons for this are conductance's lack of selectivity …
