11. Summary of the new findings of the thesis:
+ It was studied to manufacture usefully the HNF-ME new device based on improvements of the SPME device. Wherefore, the HNF-ME technique has advantages than the SPME technique: the mechanical strength is increased so the device is reusable; the film thickness is increased so it is increase limit of determination of the method and micro extracting easily in headspace of aqueous samples and air samples (dynamic HNF-ME).
+ It is found the formula to calculate the film thickness and since it compared the film thickness resulting by the formula with observation by SEM. The accordance of these two ways allow to determine the film thickness by the semi-empirical formula instead of measuring directly.
+ Using the HNF-ME device combination with the GC-FID and GC-MS to found the analysis procedures of the BTEX compound groups in headspace of aqueous samples and air samples.
+ Using the HNF-ME device combination with the GC-ECD and GC-MS to found the analysis procedures of the chlorinated short-chain hydrocarbons in headspace of aqueous samples and air samples.
+ It has estimated the analysis parameters of 4 process by Origin 6.0 software. The analysis parameters for determination of the BTEX and chlorinated short-chain hydrocarbons in the headspace of aqueous samples and air samples are compared with these of some methods, that had before.
+ Application of the analysis procedure to analyze directly BTEX and chlorinated short-chain hydrocarbons in some aqueous and air environmental samples around Ha Noi city.
+ Study on the kinetics of distribution to confirm the theory foundation for analytical sorption process of analyte from sample on the film of the HNF-ME technique.
