Abstract Details

2009, Master of Science, Miami University, Chemistry and Biochemistry.
Polymeric polyimide capillary tubing, both uncoated and coated with stationary phases of two polarities, is explored for use as capillary columns for gas chromatography (GC). These glass-free polyimide columns are flexible and their small winding radius may enhance the design of portable GC instruments. Polyimide columns with dimensions of 0.32-mm ID x 3-m L are cleaned, baked out, and coated using the static method. Coating thickness is 0.5 - 1 µm. Separations of volatile organics are investigated isothermally on duplicate sets of polyimide columns by GC with a flame ionization detector, using split injection. The columns are characterized with a sample mass load study, a column reproducibility study, and a van Deemter study. The uncoated polyimide columns are minimally capable of GC separations. The coated polyimide columns successfully separate Grob test mix alkanes, bases, and fatty acid methyl esters, and are comparable to standard fused-silica capillary GC columns.
