Guest editor's introduction to the special issue on analytical spectrometry in China

In recent years, great advances in spectral analysis have been made in its applications in various areas worldwide, including in China. It is not surprising to see that the development is out of balance, with very active research in analytical molecular spectrometry and much less work in analytical atomic spectrometry. Atomic mass spectrometry has been well developed and widely used especially in bioanalytical chemistry. In this special issue, five invited reviews are from five very active research groups in China who have more or less research experience in analytical atomic spectrometry in different stages of their professional careers. These reviews mainly include new colorimetric methodology, mass spectrometry for bioanalysis (especially for metallomics studies), and (quantum dot–based) fluorescence sensors. They are useful not only for quantitative (speciation) bioanalysis but also for imaging analysis. It should be pointed out that less active research in analytical atomic spectrometry does not mean that it is out of date: one reason is that traditional atomic spectrometry is focused on elemental analysis only. In fact, analytical atomic spectrometry is still among the main forces in various practical laboratories and it may stage a comeback with its recent progress in its applications in metallomic studies and elemental imaging analysis.
