Portable transmission Raman spectroscopy, combined with chemometric modeling, is quickly emerging as a valued technique for content-uniformity testing, given its high chemical specificity, which is particularly useful when dealing with complex pharmaceutical formulations that contain multiple components.

Raman spectroscopy is ideal for at-line or online material analysis for manufacturers of graphene and other carbon nanomaterials to do materials characterization, product quality control, and process monitoring.

A simple SERS-based method was used to identify low doses of the APIs alprazolam, codeine, oxycodone, and hydrocodone using a handheld Raman spectrometer.

Carbon black is a form of amorphous carbon. It is mainly used as reinforcement filler in automobile tires and other rubber products, but it's also used in pigments, paint, and carbon paper.

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 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).
