At NINGBO INNO PHARMCHEM CO.,LTD., we employ a multi-faceted approach to validate the performance of our chemical innovations. Our research into DAMP, a leading organophosphorus derivative for copper corrosion inhibitor in acid applications, extensively utilizes advanced imaging and elemental analysis techniques. Among these, SEM EDX analysis of corrosion inhibitor plays a pivotal role in visualizing and confirming DAMP's protective capabilities.

Scanning Electron Microscopy (SEM) provides high-resolution imaging of the copper surface, allowing us to observe the physical effects of corrosion and the presence of protective layers. Energy Dispersive X-ray (EDX) spectroscopy, coupled with SEM, enables elemental analysis of specific areas on the surface. This combination offers crucial insights into the composition of any films formed.

Our SEM analysis revealed that copper surfaces exposed to acidic solutions without DAMP exhibited significant signs of corrosion, characterized by pitting and the formation of corrosive by-products. In stark contrast, copper surfaces treated with DAMP showed dramatically reduced corrosion damage. The EDX analysis further confirmed this by detecting the presence of key elements from DAMP (phosphorus, nitrogen, and oxygen) embedded within a protective film on the copper surface. This direct elemental evidence validates the formation of a barrier layer that shields the copper from corrosive attack.

These findings are fundamental to understanding why DAMP performs so effectively. By visualizing and confirming the physical presence of the protective layer, we provide concrete evidence of its efficacy. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to advancing material science through such rigorous analytical methods, ensuring our clients receive products that deliver on their promises of superior protection.
