Spectra Heap descriptions Spectra Heap is a software product & a spectral lines database for atomic emission analysis created on the basis of the spectral tables issued earlier as separate publications. Spectra Heap contains the information about almost 100 000 spectral lines of the majority of chemical elements. This information is valuable in industrial scientific & educational spectral-analytical method laboratories. The creation of this unique electronic guide makes the spectral data use more convenient. There are lots of new opportunities that are inaccessible while using printed sources e. g. fast search of the necessary lines by various criteria work with groups of elements overlapping lines search sorting of lines by certain characteristics graphic display of results reports adjusted by the user etc. Spectra Heap is also an electronic guide on physical & chemical properties of elements. This information can be received practically in any place of the programme.
