Application Notes

Raman spectroscopy’s high analytical selectivity and insensitivity to water is well suited for process monitoring in biotechnology. Here we explore the fermentation of glucose, a common feedstock, with a commonly used microorganism, yeast. Applying multivariate tools, we can monitor the main reactants and products with high sensitivity: glucose, ethanol, and carbon dioxide.

The effect of annealing time on the charge carrier lifetime of three MAPI perovskite films is investigated using time-resolved photoluminescence spectroscopy.

Compressed tablet is the most common form of orally administered drug. The United States Pharmacopeia (USP) chapter <905> requires that dosage uniformity of such products containing less than 25 mg or less than 25% active pharmaceutical ingredients (API) by weight must be analyzed for content uniformity, which is based on the assay of each API in a number of individual dosage units.

The utility of the GladiATR diamond ATR, modified with an internal liquid light guide to illuminate the sample from underneath the ATR element, was explored to analyze the photo-polymerization of carbitol acrylate at 405 nm using 1 wt% TPO.

A compact, MEMS-based, single-photodetector NIR device, the NanoQuest, is used to distinguish different types of textiles.

The quality and stress field properties of gallium nitride (GaN) crystals must be investigated in order to refine production processes. 3D Confocal Raman microscopy is uniquely capable of the chemical c and visualizing strain in this material.
