Technical Data of DOB
1. Application field
The breath test analyser DOB Series is a nondispersive infrared specrometer. It is used for determining the ratio of natural isotopes 13Cand 12C in gases containing CO2.The main application field of the analyser is at the clinics, at the physician's officelaboratories and at gastroenterologists for investigating HP , metabolic processes and diagnosing infectious or metabolic diseases.
