title: [Method for determination research of trace germanium in the serum of cancer patients by graphite furnace atomic absorption spectrometry].
abstract: Using a tungstate-coated graphite tube, trace germanium in serum samples was determined by Zeeman graphite AAS with NH4NO3 as a matrix modifier. The sensitivity of Ge can be significantly improved. The matrix interference has been removed. The relative standard deviation is less than 3.61%. The method is simple, rapid and accurate.
