The title of the thesis: The Identification of Substances in Real Samples Using Portable Raman Spectrometer The portable Raman spectrometer Ahura First Defender is a device designated for identifying unrecognized solid and liquid substances. The aim of this diploma thesis was to test the efficiency of the portable Raman spectrometer First Defender and to draw up a draft of the methodology for its manipulation. The objects of the investigation were the accuracy of results and collection of findings coming out of measuring tests using the device mentioned above. The introduction part briefly describes problems of chemical monitoring within Fire Rescue Service of the Czech Republic. As a partly solution of the problems could be the use of the portable spectrometer First Defender. Further are described problems of sampling and possibilities of sample detection through means of chemical reconnaissance. As next, there is described the device itself including the principle of Raman effect that allows the device to identify unrecognized solid and liquid chemical substances. The practical part explains the procedure and the way of applied measuring tests when using the device. The results are summarized in charts and the percentage of successful performed tests analyzed in charts. Findings concerning the manipulation with the device, methods for sample modification and the influence of sample matrix on the identification of selected chemicals in observed samples are introduced in the discussion. Professional knowledge and experience were used to draw up guidelines for the identification of substances in real samples conceived as general informational source describing procedures, rules, and recommendations. Upon all outcomes and findings, there was confirmed the hypothesis of greatly beneficial using Raman spectrometer in Fire Protection Units when identifying unknown substances at places of intervention at the end of the thesis.
