PI-200-I

Multi-channel Process Raman Analyzer

With HORIBA’s PI-200-I Process Raman Analyzer, you can do more with less. Integrated with a custom-built fiber multiplexer, a single analyzer can monitor up to 17 different sampling points across multiple process streams—replacing the need for numerous separate analyzers. This not only simplifies operations but also reduces costs, improves efficiency, and delivers real-time insights you can trust. The PI-200-I is engineered to give you maximum performance with minimal complexity.

Multiplexer Features

Optical Multiplexer
Sequential Analysis
Sequence and data frequency is determined by end-user
Correlate the grab samples downstream to PI-200-I collection time

The fiber multiplexer automatically routes the excitation laser light and collected Raman scattering signals between various sampling probes, allowing for sequential analysis of multiple locations within the process. This capability is especially valuable in complex processes where monitoring various streams, reactors, or stages of production is essential for comprehensive control and optimization. The fiber multiplexer is specifically designed to operate seamlessly across all channels and probes, ensuring that signal quality remains uncompromised across all of the sampling points of the analyzer's multiplexer.

Integrating a fiber multiplexer into the PI-200-I transforms the analyzer into its fullest potential, creating a highly scalable system capable of handling large, distributed process environments automatically and with ease by the end user.

Petrochemistry is a process in which basic products are generated using oil and natural gas as raw materials in order to produce base set of chemical compounds (derivatives) for diverse related industries, such as synthetic fibers and synthetic resins. In Japan, naphtha is mainly used as the raw material for this process. In other countries, however, less expensive manufacturing of derivatives such as ethylene manufacturing from non-naphtha materials (e.g., shale gas and coal).
