Abstract

The present invention provides a method for analyzing one or more constituent of exhaled breath. The method includes contacting a biochip with the exhaled breath such that the constituent interacts with the biochip and becomes reversibly immobilized thereon. The breath constituent is desorbed from the biochip in a mass spectrometer and the desorbed constituent is subjected to mass spectrometric analysis. The spectrum that results includes peak(s) that are representative of the constituent, allowing its characterization and, optionally, its quantification.
