ELECTROSONIC SPRAY IONIZATION METHOD AND DEVICE FOR THE ATMOSPHERIC IONIZATION OF MOLECULES
摘要
There is described a device and method for generating gaseous ions of a sample material such as molecules in solution at atmospheric pressure. The device includes a conduit for receiving a solution containing the material to be ionized and form a stream. A jet of gas at supersonic velocity is directed at the stream and interacts therewith. Droplets are formed and by the adiabatic expansion of the gas and vigorous evaporation of the solution gaseous ions are generated. In the method a stream of the sample solution is delivered from a conduit with an electric potential. A gas jet at supersonic velocity interacts with the delivered solution and through the action of adiabatic expansion of the gas and evaporation of the solution gaseous ions are formed.
