Sažetak
Experimental MS response were measured for 36 different saturated and unsaturated volatile organic compound (VOC) containing carbon, hydrogen and halogen atoms. Chemical structure was encoded using various molecular descriptors. A quantitative structure-property relationship model was established using the multiple linear regression models. The cros-validation ability of the created model was estimated by leave-one-out cross validation pocedure. Error in cross-validation of response factors was calculated by cross-validation procedure and was 15%, which is sufficient for the determination of VOCs in the air. The proposed procedure can be used for simultaneous qualitative and quantitative determination of volatile organic compounds in the atmosphere.
