A justified question: for half a century, AAS users had to put up with abstract numerical values.

How they come about and whether they are actually accurate remains a secret. The High-Resolution Continuum Source (HR-CS) AAS used in the contrAA® series from Analytik Jena provides the AAS user with significantly more information. Thanks to the combination of a xenon lamp covering the entire relevant wavelength range, a high-resolution spectrometer and a CCD-detector, it has become possible to visually represent the absorption spectra of samples...
