Anodic redissolution polarography is undeniably the most effective analytical method for the detection of impurities contained in mercury.

Analytical control is now entrusted to EAG Laboratories, an independent laboratory.

The method used is Glow discharge mass spectrometry or

GDMS  (Glow Discharge Mass Spectrometry)

The analysis is now focused on 74 elements and no longer on 21 with the previous polarography method
