SENTINEL Raman Process Spectrometer
- The Unilab universal sampling probe is a high performance fiber optic probe for dispersive Raman spectroscopy.
SENTINEL® is a Raman spectrometer developed for process control and automated lab applications. The system utilizes an On-Axis spectrograph, optimized for Raman spectroscopy and one standard grating covering the most widely used Raman signature range. The patent pending curve slit correction for aberration free imaging, low noise CCD and innovative technology in signal processing result in excellent signal to noise ratio and maximum performance.
The instrument has no moving parts, being free from mechanical wear it requires low maintenance. The integrated diode laser provides 532 nm or 785 nm with various power levels available. The system comes equipped with a Class 3 light-tight safety enclosure with interlocks in 19" rack configuration.
The SENTINEL® is compatible for a choice of laboratory, siteglass and process immersion probes, allowing real time process monitoring from a remote location. The Raman UniLab Research probe is a high sensitivity device designed to utilize both large illumination and collection areas. The large area illumination design reduces the susceptibility of sample misalignment as well as decreases the effects of heterogeneity issues of the sample, resulting in superior averaging capability.
The SENTINEL® utilizes Sure_Cal® 1)calibration technology, a method for achieving a standard Raman spectrum that has both short and long term precision and accuracy. The Sure_Cal® technology allows for the collection of the standard spectrum independent of any instrument instabilities. The Raman spectrum of the sample, the laser/neon spectrum and the neon spectrum are collected simultaneously.
