Patent ID: 7972277

Claim:
A method for analyzing exhaled breath using a breath analysis apparatus, said method comprising: providing the breath analysis apparatus which includes a vessel; an injection port of the exhaled breath provided at one end of the vessel; an outlet port of the exhaled breath provided at the other end of the vessel; a cooling unit provided inside the vessel; an electrode zone provided in the vicinity of the cooling unit; a counter electrode zone provided inside the vessel; and a chemical substance detection unit provided in the vicinity of the counter electrode, said exhaled breath contains water vapor and a volatile organic compound, injecting the exhaled breath from the injection port into the vessel; condensing the exhaled breath on an outer peripheral surface of the electrode zone by cooling the electrode zone with the cooling unit; forming charged fine particles from the condensed breath; recovering the charged fine particles into the chemical substance detection unit by an electrostatic force; and detecting the volatile organic compound included in the charged fine particles recovered.
