Stability testing is a critical component in the development and approval of active pharmaceutical ingredients (APIs) and finished pharmaceutical products (FPPs). This process involves evaluating how various environmental factors, such as temperature, humidity, and light, affect the quality and efficacy of drugs over time. Understanding stability is vital for ensuring that medications remain safe and effective throughout their shelf life, thus protecting public health.


The Benefits of PQQ

Corrosion is another major issue in chilled water systems that can lead to equipment damage and unscheduled downtime. The presence of dissolved oxygen, carbon dioxide, and chlorides can exacerbate corrosion processes. To mitigate this risk, corrosion inhibitors, such as nitrites, phosphates, or azoles, are added to the chilled water. These inhibitors form a protective film on the metal surfaces, effectively shielding them from corrosive agents. Implementing a tailored chemical treatment program not only prevents corrosion but can also extend the lifespan of the system components.
