Atmospheric Condensate Collector and Electrospray Source

An atmospheric condensate collector and electrospray source apparatus. The apparatus has a cooler having a surface with a sharp point. The cooler generates a condensate from ambient atmosphere exposed to the cooler. A ground electrode is electrically and mechanically separated from the cooler. A high voltage power supply switchably provides a high voltage between the sharp point of the cooler and the ground electrode. A controller is electrically connected to the cooler power supply and the high voltage power supply. The controller controls the operation of the cooler power supply and the high voltage power supply. The atmospheric condensate collector and electrospray ionizer apparatus generates the condensate and generates particulate spray from the condensate in response to command signals issued from the controller. In some embodiments, an analyzer is provided to analyze particles of the spray to determine the chemical composition of the condensate.
