Popis:	A prototype mobile mass spectrometer for direct detection of heavy metal traces in water is proposed. The instrument allows automated dosed injection of liquid samples (2.5–20.0 μl) into the lock vacuum chamber of the instrument, extraction of salts containing target components for their following introduction into the high-vacuum chamber of the instrument, and determination of the component concentrations in the initial sample by means of a portable magnetic mass spectrometer equipped with an original electron-impact ion source. Experimental testing of the spectrometer using aqueous solutions containing Zn, Fe, Cu, As, and Cd shows that the instrument can detect heavy metals in water, including salt water, at concentrations ranging from 1 mg/l to 10 μg/l. The experimental results are discussed.
