Abstract
Sol-gel beds and deposits are utilized for SERS analysis of liquid analytes. Measurements are made at multiple points along the length of a column or channel to increase, very significantly, the speed of analysis, and use of the same medium to both separate the chemicals and also for SERS greatly reduces the complexity of such apparatus and enhances the efficiency of the method.
