[Gas-phase chromatography in the rapid bacteriological diagnosis of infections. Contributions and limitations of this technic].
Gas-liquid chromatography has been used directly on clinical specimens as a method for presumptive diagnosis of anaerobic infections. This technique proved to be valuable and reliable. Combined with a Gram stain, it offers the possibility to differentiate in less than 1 hour aerobic from anaerobic infections by means of detection of volatile fatty acids (short chain monocarboxylic acids) others than acetic acid.
