On the Retention Time of Odour from the Human-body

Methods of mass-changing and GC-MS with SPME were applied to the study of retention time of odour from the human-body in a definite space.As shown by the experimental results,the retention time of the human-body odour within a room,with av.temperature of 25 ℃ and av.value of relative humidity of 64%,attained to at least 60d,and stability of the odour in respect to the quality was observed at least within 20d.With the help of the method GC-MS with SPME,25 ingredinets commonly found in human-body odour were detected.
