ANALYZER FOR NITRIC OXIDE IN EXHALED BREATH WITH MULTIPLE-USE SENSOR

摘要

A high-sensitivity analyzer for nitric oxide in exhaled breath at levels of 200 ppb or less with a sensor containing cytochrome C is rendered capable of multiple uses without the need for installing a new sensor for each use. This capability is achieved by regenerating the analyzer after each use by purging the sensor and surrounding regions with NOx -free air in a controlled manner, preferably in pulses separated by equilibration periods.
