Despite its small 52 x 39cm footprint size, this Raman spectrometer is a high performance instrument capable of achieving resolutions up to 3cm^-1. It also comes with a full featured software with many built in analytical features. The spectrometer is equipped with a high throughput proprietary fiber bundle probe and built-in Princeton Instrument CCD that is TE-cooled to <-70°C, yielding excellent light throughput, sensitivity and resolution needed to confidently use Raman to answer critical QA/QC and analytical questions.

There is also an external sampling module which can be connected via the fiber bundle probe. The base laser excitation wavelength is 785nm, though other excitation wavelengths are available. The base version has a standard resolution (SR) of 5cm^-1 (wavelength coverage: 140 - 3300cm^-1). A high resolution (HR) version of 3cm^-1 (wavelength coverage 140 - 2000cm^-1) is also available.

Software

The Lumuc I Raman System is operated through RamanSoft, a proprietary software for data acquisition, data processing, and data analysis for its Lumuc I Raman systems. The software functions as an instrument control center permitting user to set CCD temperature and integration time, control the laser shutter and laser power. In addition, RamanSoft has a user-friendly interfaces which give easy access to advanced features including automated spectral library searching, qualitative and/or quantitative spectral analysis, and real time process monitoring.

The program provides a comprehensive suite of data handing features designed to expedite data processing and analysis. These include several spectral smoothing algorithms for noise reduction, the ability to normalize spectra to different spectral features and /or to laser power,and Lumuc's proprietary algorithm for background removal to enable the user to obtain consistent spectra across different background conditions. These features along width quantitative procedures for peak intensity and peak area provide a full range of processing and analysis features.

Key Features

• Software control of laser power, CCD gain and digitization rate
• Auto system calibration with calibration kit (Optional)
• Automatic & manual background removal, signal averaging, normalization, spectrum overlay
• Peak ID, peak area, SpectrumSearchTM, SpectrumPredictTM, Real Time Monitoring
• User-definable automation sequences for seamless data processing / data analysis
