Quality originates from design (QbD), and its essence is to test and screen the process parameters to determine the design space and control space, and to adopt appropriate control strategies to ensure the production of qualified products. In order to achieve this goal, process control analysis (PAT) plays a very important role in process monitoring, analysis and control. PAT is to design, analyze and control the production and processing process by timely measuring the key quality and performance characteristics of raw materials and materials under processing. The analysis in < br/ > PAT is a comprehensive analysis involving multiple disciplines, and its process runs through the whole production process. Therefore, there are a variety of analysis tools to strengthen process control and improve product quality. At present, online spectroscopy is widely used, including near infrared spectroscopy (NIR), Raman spectroscopy, fluorescence spectroscopy (LIF) and so on. Raman spectroscopy has become a widely used PAT tool because of its fingerprint characteristics. < br/ > on-line Raman spectrometer is an instrument for real-time monitoring and analysis of chemical composition in samples. It uses Raman spectroscopy to obtain information about the composition of the sample by measuring the scattering spectrum of the substance in the visible region. This technology is widely used in industry, agriculture, food, pharmacy and other fields.

◆ Excellent performance: scientific research-grade spectral performance, with the advantages of high resolution and high sensitivity; < br/ > long-distance test: configurable length of 1-100m composite optical cable to adapt to the complex detection scene; < br/ > durable: the device can still operate stably in the harsh working environment to ensure continuous high-quality spectrum acquisition. The combination of durable materials and precision technology ensures the long life and reliability of
