Two procedures are described for the spectrographic determination of 0.002 to 3 ppm of boron in graphite. In the first method, preliminary concentration is carried out by the removal of the graphite by ashing in the presence of La/sub 2/O/sub 3/. Then the boron in La/sub 2/O/sub 3/ is determined by the carrierdistillation method. In the second method, a sample in the form of powder is compressed into pellets with the aid of a phenol-formaldehyde resin as binding medium, and the pellets are arched at 7 amp d-c. By means of display microphotometry, the peak height of B at 2497.73 A is compared with that of the NO( gamma ) band component at 2497.14 A. (auth)
