Detecting Methanol Contamination in Hand Sanitizers

November 11, 2020

This case study demonstrates how the Tactic-ID GP handheld Raman analyzer was used to detect contamination in a commercial hand sanitizer. 

Raman Analysis of Si Crystallinity

September 01, 2011

While crystalline silicon (c-Si) is still the material of choice for modern solar cell manufacturing, the drive toward lower cost, more efficient solar cells is prompting a renewed interest in thin-film amorphous silicon (a-Si). In light of this, it is more important than ever to have the ability to quickly identify Si crystallinity, both qualitatively and quantitatively. In this application note, we evaluate how a portable Raman spectrometer can be used in conjunction with a portable video microscope to measure crystallinity.

A Comparison of Raman Analysis of Carbon Nanotubes

September 01, 2009

A new Raman spectrometer system, innoRamâ„¢, has been developed to provide research-grade performance in either a lab or a mobile environment. The Raman analysis of carbon nanotubes using innoRam in comparison with a Raman spectrometer using a conventional front illuminated CCD demonstrates distinctive improvements for innoRam in both sensitivity and signal-to-noise ratio (SNR).
