Application of Compound Composer Software in Screening Organic Compounds in Water Sample

Gas chromatography coupled with mass spectrometry( GC- MS) was investigated using compound composer software through several monitoring activities. The standard solutions of nineteen organochlorine pesticides were quantitatively and semi- quantitatively tested. The relative deviations of the semi- quantitative results for2 mg / L standard solutions ranged from- 94% to 42%. The water samples from four rivers were determined using this software. Eleven organic compounds were found besides Pthalate esters( PAEs),dibenzofuran,methyl almitate,- ethyl- 1- hexanol,benzothinaol,ethanol,2- phenoxy-,and 2-( methylthio)- benzothiazol. The compound composer software was also successfully used in the environmental emergency monitoring. The pollutant 2- methoxy- 6- methylaniline was detected to provide evidence for environmental management. The compound composer software could realize the rapid and quantitative and semi- quantitative tests without the standard solution. This presented an applicable value in the environmental emergency monitoring.
