cze	Optimalizace SPME pro stanovení nitrosloučenin pomocí GC-MS	Byla provedena optimalizace pro stanovení aromatických nitrosloučenin pomocí GC-MS. Optimalizace byla provedena metdou DEO. Nalezené podmínky byly testovány na reálných vzorcích získaných z pokusných odpalů náloží.	SPME; GC-MS; aromatické nitrosloučeniny
eng	Optimization of SPME for determination of nitro compounds using GC-MS	SPME is extraction technique, which is compatible with gas chromatography. The sensitivity may be good for determination of very low concentration levels. In this paper is this method used for determination of aromatic nitro compounds. Mixtures of aromatic nitro compounds and concentrated nitric acid are potentially useful as improvised explosive devices. Therefore, it is necessary to find sensitive analytical procedures for the determination of residues after the explosion. Connection gas chromatography with mass detector was used for analysis. It is necessary to optimize conditions SPME (time, temperature, sorption and any amount of NaCl). To optimize the use of statistical techniques DEO. Suitable extraction conditions were found with this method. These conditions were tested on real samples after the explosion.	SPME; GC-MS; aromatic nitro compounds
