| Abstract: | A technique of atomic emission determination of traces of toxic elements in dimethylaminoborane with detection limits of n·10–5–10–8 wt. % has been developed. To reduce the detection limits, a technique of separation of the basic component in the form of boron fluoride, with concentration of microimpurities on a graphite collector, was used. |
