Comparison of gas chromatograph-mass spectrometry (volatile organic compounds) of adsorbent bandages used by healthy and Cervical Cancer-affected women. After usage of the adsorbent pads during 8 hours, these were subjected to an analysis by gas chromatography-mass spectrometry. The compounds were obtained by using the experimental conditions: hexane at 4°C with DB-column of 1.25 mm×60 m×0.25-μm and Helium gas carrier by employing Agilent gas chromatography-mass spectrometry equipment. The upper chromatogram represents a healthy woman, and the lower chromatogram from a Cervical Cancer-affected patient. The x-axis represents the time retention in minutes, while the y-axis the curve area. The graph is showing an example of mass spectrum of the following organic compounds: Oxirane; 2-methyl-3-propyl-trans; 5 H Tetrazol-5-amine; Eicosane and Dibutyl phthalate (DP) presented in the healthy women (Healthy chromatogram), while the 3 Ethyl-3-methyl heptane; 3,3 Dimethyl-1 [2 carboxyphenyl] triazine; and DP in the cancer patient (Cervical Cancer chromatogram), where a clear difference in DP concentrations between women was observed (vertical red rectangle). Chemical structure of the organic compounds is also showed
