Abstract
Reversed-phase high-performance liquid chromatography (HPLC) is directly coupled to helium microwave-induced plasma mass spectrometry (He MIP-MS) for the element-selective detection of halogenated organic compounds. Absolute detection limits are approximately 50 pg Br for brominated compounds, 1 pg l for iodinated compounds, and 10 ng Cl for chlorinated compounds. The linear dynamic range for Br- and l-containing compounds is 3–4 orders of magnitude. However, the linear range for chlorinated species is severely limited by high background at m/z = 35. The relative standard deviation for repetitive injections is less than 10%. The helium microwave-induced plasma is operated at moderate powers (300–350 W) and with a total helium consumption of 6–8 L/min. The effect of organic solvents on the background mass spectrum is investigated.Keywords
