RMP-300 Series Portable Raman Spectrometers

he JASCO RMP-300 Series portable Raman spectrometer system incorporates a fiber optic probe with a small X-Y-Z stage, compact laser, a high-throughput spectrograph and Peltier-cooled CCD detector. No special utilities, such as coolants, are required allowing the system to be used almost anywhere in the field or in a laboratory. The flexibility of optical fiber coupling enables remote measurements by locating the probe right at the sample. The fiber optic probe features an integrated CCD video camera for sample positioning and capturing of digital sample images. All operations are performed by the dedicated software package based on JASCO Spectra Manager II™. The RMP-300 Series consists of six models, the RMP-310, 315, 320, 325, 330, and 335, ranging from small, portable units suitable for in-situ measurements to research-grade systems to provide capabilities for a wide range of application requirements. The RMP-300 system is controlled using Spectra Manager II™, JASCO's powerful Windows-based cross-platform spectroscopy software package. The system is capable of both laboratory work and on-site measurements in the fields of process control, QC, forensics, art conservation and mineralogy.

    RMP-300 Applications

• In-situ measurement of UV cured resin
  
  
  
  The figures outline an application to monitor the curing process of a thin-layered UV-curable resin with UV light irradiation. Raman spectroscopy is very sensitive to the change of the C=C bond in alkene or aromatic compounds, therefore, the intensity change of the C=C bond in the non-cured resin can be directly detected during the UV curing process.
