| Abstract | The combination of Gas chromatography (GC) for separation and Flame Ionization Detection (FID) for detection and identification of the components of a mixture of compounds is a fast and strongly proved method of analytic chemistry. The area of application of such a system extends from volatile to non-volatile components. The objective of this thesis was to design a combined High-speed miniature screening Gaschromatograph along with a Flame Ionization Detector for quick, quantitative and qualitative analysis of gas components. This combined GC-FID system is suitable for detecting the volatile and semi-volatile hydrocarbons present in a gas mixture. The construction made it less expensive, easy to use and movable. The complete gas path was developed using metal, PolyVinyle Chloride (PVC) and tefflon flow pipes and using Swagelocks for connection with the GC and the FID. On/off valves, temperature and flow sensors and their interface electronics were used for controlling purpose. A Microcontroller was programmed so that it measmes the temperature and gas flow using the sensors and then can control and regulate them using the electronics and valves. A pocket PC with its touch screen served as an user interface for the system. A software was developed for the pocket PC, which makes the communication possible with the Microcontroller over a RS232 serial interface. The system parameters can be indicated in the Pocket PC as simple text and also the analysis result can be displayed |
