Another way of dealing with solid samples would be to directly vaporize the sample and excite it by using a laser pulse or a spark between electrodes. Single- and double-layer coatings were investigated using potentiodynamic polarization, electrochemical impedance spectroscopy, and plasma atomic emission spectroscopy to assess corrosion characteristics in vitro (samples in SBF at 37 °C and pH = 7.3 for 30 days). Forensic experts use this method to study soil samples found at the crime scenes and ascertain their origin. 3 Flame Atomic Emission Spectrometer . The disadvantages of this method include a huge cost of infrastructure maintenance and operating expense, the presence of several emission lines or spectral interferences and the necessity of having samples dissolved in solutions.
