Transition from analogue-to-digital nuclear electronics for precise gamma radiation spectroscopy: advantages and limitations

In this paper, digital signal processing for precise gamma ray spectroscopy is presented. The basis of this system is a 14bit waveform digitizer which samples the output of pre-amplifier signals directly. The advantages and limitations of the digital spectrometer compared with analog spectrometer has been tested and analyzed from precise gamma ray spectroscopy point of view. The results shows t...

Indirect Determination of Ascorbic Acid by Atomic Absorption Spectroscopy

A new and simple method followed by atomic absorption spectrometry has been developedfor indirect determination of ascorbic acid (AA). The proposed method was based on the oxidationof AA to dehydroascorbic acid with Cu2+cation(200mgL-1)in an ammonium thiocyanatesolution atpH2.4. AA reduces Cu2+to Cu+followed by the precipitation of Cu+ with SCN-. Then, the excess ofCu2+in the solution was measu...

Forensics Atomic Absorption Spectroscopy

Atomic absorption spectroscopy Atomic absorption spectroscopy (AAS) was developed in the early 1950’s by Alan Walsh. It works on the principle that certain elements absorb certain wavelengths, and this level of absorption is characteristic of each element. Also, electrons in atoms can only exist in particular energy levels, and when an electron moves to a higher energy level, electromagnetic ra...
