Although the availability of large telescopes and more sensitive detectors has led to a much more complicated picture of white dwarf spectral classes and abundance patterns as compared to the situation ten years ago, it still remains true that the vast majority of white dwarfs show a pure hydrogen spectrum even in temperature regions where the presence of other elements with e.g. solar abundances would be easily revealed.
