	Ion trap mass spectrometry is an excellent tool for identifying both large and small molecules and determining their molecular structure.
	We have designed and constructed an ion trap mass spectrometer and we try to implement an efficient method of spectral exploration for organic pollutants detection.
	The mass spectrometer has an external ion source of electron bombardment type. The radius of the annular electrode is 7mm, and distance between the end-cap electrodes is 10mm. The detection of the ions will be made by a Faraday cage type collector, or by a channeltron in the case of the very small current.
	A GC-MS coupling is stipulated for routinely analyse sample that cannot be tested with other methods.
