Process Analytical Technology (PAT) refers to a system for designing, analyzing, and controlling manufacturing processes through timely measurements of critical quality and performance attributes. It aims to ensure that products are consistently produced to meet predefined quality standards, enhancing efficiency and reducing waste. PAT integrates various tools and techniques, such as spectroscopy, chromatography, and data analytics, to monitor processes in real-time. By utilizing these technologies, manufacturers can make informed decisions, optimize production, and ensure compliance with regulatory requirements, ultimately leading to improved product quality and safety.
