Quantitative Analysis of a Water-soluble Polymer Using the i-Raman EX Spectrometer

In this application note, we’ll explore some of the capabilities of the TacticID-1064 ST handheld Raman system and how it can be used to measure and identify illicit substances through both transparent and opaque containers without fluorescence issues that generally associated with 785 nm Raman systems.

Dispersive Raman spectroscopy has increasingly been implemented for material identification due to its portability and sampling flexibility. When choosing a Raman instrument, a primary concern is the wavelength of the laser that is integrated into the Raman spectrometer system. Though the Raman shift of any material is only related to the material’s specific chemical str...

At a crime scene, a police officer collects a fiber sample that may prove to be invaluable evidence in identifying a criminal or exonerating an innocent person. In this study, we show how Raman spectroscopy, which has been studied extensively for forensic fiber analysis, is a perfect fit for this scenario because of the high selectivity of Raman signatures, non-destructi...
