Stationary phase deposition based on onium salts
| DWPI Title: Gas chromatography column for detecting pollutant, has column formed using conductive/semiconductive column material, organic layer formed by reduction of onium salt, bonded to column and stationary phase material bonded to layer |
| Abstract: Onium salt chemistry can be used to deposit very uniform thickness stationary phases on the wall of a gas chromatography column. In particular, the stationary phase can be bonded to non-silicon based columns, especially microfabricated metal columns. Non-silicon microfabricated columns may be manufactured and processed at a fraction of the cost of silicon-based columns. In addition, the method can be used to phase-coat conventional capillary columns or silicon-based microfabricated columns. |
| Use: For detecting chemicals, pollutants, toxic industrial chemical, high explosive, and chemical and biological warfare agent. |
| Advantage: The gas chromatography column is economically manufactured. |
| Novelty: A gas chromatography column has a column formed using a conductive or semiconductive column material, an organic layer bonded to inner wall of column, and a stationary phase material bonded to the organic layer. The organic layer is obtained by reduction of an onium salt on the column material surface. |
