Raman Probe Heads & Optics

Pilot Probes
for Process Analytics

Pilot-S probe   
 

The Pilot™ series of Raman probes has been developed for optimal performance with all the Raman analyzers in the RamanRxn Systems™ family. The RamanRxn Systems family of instruments is ideal for analyzing, monitoring, and controlling chemical processes. The combination of the Pilot line of Raman probes and the RamanRxn3™ Analyzer for classified locations system yields both a powerful Process Analytical Chemistry (PAC) and Process Analytical Technology (PAT) analyzer for in situ analysis or control, from the safety or optimization laboratory to the manufacturing reactor.

The Pilot series is available in two styles. The Pilot-S probe is ideal for small reactors, while the Pilot-E has been designed for large reactors—up to 15 feet in size. Pilot-E probes can be used with glass-lined reactors, commonly found in pharmaceutical manufacturing facilities, without reactor modification. The modular design of the Pilot series of probes allows the sampling point to be customized for each customer's reactor, thus removing the need for sampling slip stream. This, in turn, will reduce maintenance cost, eliminate a potential failure mechanism, improve process safety, and reduce initial installation cost.

All Pilot probes utilize a single fiber for excitation and another for collection. For laboratory equipment, this provides a robust interface and sampling versatility. For process equipment, single fibers allow reduced cost for long runs of fiber as compared to multi-fiber collection designs. Single collection fibers also permit simultaneous multi-channel operation on a single analyzer. Standard telecommunication fiber diameters (<100 microns) are used to increase mechanical stability. This results in fewer broken fibers, increased safety, and lower maintenance costs.
