Determination of different analytes through electro-analytical techniques is easy but can we rely on the obtained results without validating them by standard analytical tools as HPLC, GC, ICP-OES etc.
For example if we quantify some drugs from pharmaceutical products through electrochemical techniques. Can we rely on these results without validating them?
i think it can be validated by using stochiometric calculation or mathematical equation instead of any instrumental technique for example Nernst equation , determination of electrode potential of half cell and pH meter Antilog[H]+ etc @J@amil Ahmed Buledi
Electrochemistry has very poor molecular discrimination for most organic compounds. A high resolution physical separation method (GC or LC) combined with a tunable spectroscopy or mass spectrometry is well accepted because impurities can be seen in small amounts and automation is readily available for multiple samples. Flow methods are more efficient and are more easily calibrated.
