PAT, or Process Analytical Technology, is a system used in manufacturing to monitor and control processes in real-time. It helps ensure that products meet quality standards by analyzing data during production rather than after. This proactive approach can lead to improved efficiency and reduced waste. The main goal of PAT is to enhance the understanding of processes, allowing for better decision-making. By integrating tools like spectroscopy and chromatography, manufacturers can gain insights into the chemical and physical properties of materials, ensuring consistent product quality and compliance with regulatory requirements.
