An electrostatic precipitator for preparative gas-liquid chromatography.
The effect of the operating variables of electrostatic precipitators on the recovery and structure of methyl esters and related aerosol forming compounds collected in preparative gas-liquid chromatography was studied.Aerosol formation was prevented by AC or DC voltages of 5000 to 12000 volts. AC was more effective than DC but caused changes in structure which were detectable by both thin-layer and gas-liquid chromatographic methods of analysis.An apparatus of simple construction and operation was designed for the collection of methyl esters and its use demonstrated with several model compounds.
