This paper presents two components of a ceramic analytical system-a capillary column and a flame ionization detector designed and produced using photoimageable thick-film dielectric Fodel QM44F combined with a low temperature cofired ceramic tape. The microfluidic components are integrated onto a single piece of alumina substrate, dimensions 65 x 50 mm(2), and have incorporated into them thick-film platinum heaters which ensure temperature control. The ceramic analytical minisystem is intended to detect-on the basis of ion current measurements-the presence of hydrocarbons in the analyte being passed through the capillary column and burned in the combustion cavity of the flame ionization detector. Ionic current in the range of nA was detected after introducing the analytes into the separation column.
