Abstract (en)

The atmosperic-pressure ionization device for connection to an analysis device especially a mass analysis device, comprising: a) an atmospheric-pressure ionization chamber; b) a passageway configured for delivery of ions to the analysis device; c) a sample support positioned within said ionization chamber; d) a matrix placed on said support and containing an analyte; e) a laser for directing laser energy to said sample and to induce ionization of said analyte to form analyte ions; f) means for directing at least a portion of said ionized analyte into said passageway. The sample support comprises a tube configured for delivery of the sample to an exit of the capillary. The laser is directed to said exit to induce ionization of said analyte at said exit. The sample is flowing through the tube to said exit. The tube is preferably a capillary tube. <IMAGE>
