Stabiliteettitestauksen

Stabiliteettitestaus, or stability testing, is a crucial process in various fields, most notably in pharmaceuticals, chemistry, and materials science. It involves subjecting a product or material to defined conditions over a specific period to evaluate its stability. The primary goal is to determine how the quality of a product changes over time under the influence of environmental factors such as temperature, humidity, and light. This information is vital for establishing recommended storage conditions, determining shelf life, and ensuring the product remains safe and effective throughout its intended use.

In the pharmaceutical industry, stability testing is a regulatory requirement. It helps to understand how a drug's active ingredient degrades, its physical and chemical properties change, and whether any new impurities are formed. This data is essential for approving a drug for market and for setting expiration dates. For chemical compounds, stability testing can reveal their reactivity and how they might decompose or react with their surroundings, which is important for safe handling, storage, and application. In materials science, it assesses the durability and lifespan of materials when exposed to various environmental stresses. Different types of stability tests exist, including accelerated stability testing, which uses higher stress conditions to predict long-term stability more quickly, and real-time stability testing, which monitors the product under recommended storage conditions over its actual shelf life.
