  • 532-nm Handheld Raman Analyzer
Dec 2009
BaySpec Inc.Request Info
FREMONT, Calif., Dec. 23, 2009 – BaySpec Inc. has unveiled a handheld 532-nm Raman analyzer that provides a cost effective way of performing nondestructive measurements for portable field applications, including gemstone analysis and validation, minerals and rocks, with easy adaptations for gas or liquid sampling.

The Xantus-1G-0532 features no moving parts, rugged packaging, an onboard full functional computer and a rechargeable/replaceable lithium-ion battery. An integrated 532-nm laser excites the sample at the point of measurement, while the efficient volume phase grating-based spectrograph disperses the spectra onto a sensitive CCD array for digital output to the host.Bayspec_532nmRaman.jpg

Proprietary Micro2020 Windows-based software is included with an intuitive streamlined user interface and can output data in txt, csv or spc format. A baseline correction function is intelligently built in, facilitating reduction in fluorescence interference while accounting for drift in background. The analyzer can transmit data to centralized facilities via WiFi networks or Bluetooth 2.0.

For mineral identification, x-ray diffraction and electron microscopy are labor intensive, time consuming and impractical for field applications. Raman spectroscopy, however, does not require destructive sampling or elaborate sample preparation. It shoots a laser beam at the sample and the laser excites atoms within the sample, which then emit a very weak light of a wavelength in a pattern characteristic of the material. A spectral "fingerprint" is collected, and spectral analysis is performed to identify the unknown substance.

The analyzer is available also in 785- and 1064-nm excitation wavelengths.
