In this application note, the use of Raman to monitor the fermentation of glucose (a common feedstock) with yeast is explored.

The detection of hydrogen isotopes and helium in metals has a wide range of applications from hydrogen embrittlement studies to tritium retention in fusion reactor wall tiles.

Disposable ATR slides have particular benefits when analysing packaging adhesives.

This application note shows an example of peptide sequencing in a standard mixture, diluted and directly infused into the API inlet.

Raman spectroscopy is emerging as a tool to accurately diagnose gout and pseudogout for arthritis sufferers.

SERS has the potential to be use instead of fluorescence-based biosensors. One research group are studying the influence of the supporting hydrogel matrix material on pH assay performance.

Photoluminescence is proportional to the number of charge carriers in the perovskite and, therefore, is sensitive to charge transfer into adjacent layers. This makes photoluminescence-based techniques invaluable for investigating the performance of new extraction layers.

Diamond ATR provides a simple and effective alternative to KBr pellets for the infrared analysis of powders.

Benchtop NMR has many potential lithium-ion battery QA/QC applications, as the well-resolved spectra of the small organic molecules and ions are ideally suited for quick, convenient analysis.

Non-invasive insight of gilded paint samples using infrared microscopy accessory.

The landscape of controlled substance analysis is changing with compact mass spectrometers.

Candidate materials for optical in vivo oxygen sensing were evaluated in a relevant in vitro environment through careful control and monitoring of the solution temperature and dissolved oxygen concentration.

A method to correct for slight variations in the wavenumber and intensity response of multiple units is described, achieving better than 99.5 % agreement.

One important example of the utility of benchtop NMR instruments is the ability to measure self-diffusion coefficients, which can be used to extract physical information about a sample.

A flow setup will be used to monitor the formation of ethyl ethanoate over time and at different temperatures. Using this data, the activation parameters will be calculated using an Eyring–Polanyi plot.

Pro-Lite describe a new class of spectrometers developed by Wasatch Photonics.

This note outlines the basics of the ATR method, providing the analyst with the information they require to gain the most out of the technique.

A RISE system incorporates the advantages of both Raman imaging and SEM in the same vacuum chamber to facilitate the most in-depth characterisation of a sample.

This application note describes the measurement of NO2 using the m/z 46 peak and the NO/NO2 ratio in a research application.

Benchtop NMR has many advantages over similar analytical techniques due to its high degree of chemical specificity, especially when combining information from multiple chemical nuclei. Here, it is used to identify good or bad feedstock from a single, quick measurement.
