Description

General description

A wide range of MagniSolv deuterated solvents with extremely low residual water, excellent chemical purity, and the highest isotopic enrichment available can satisfy the most demanding requirements of researchers. Depending on application and sensitivity of the NMR spectrometer our offer solvents with deuteration degrees between 98% and 99.96%. In case of all the water soluble deuterated standard products, water content is specified according to both Karl Fischer and NMR.

Application

• Sensing the Bactericidal and Bacteriostatic Antimicrobial Mode of Action Using Raman Deuterium Stable Isotope Probing (DSIP) in Escherichia coli.: This research demonstrates a novel application of Raman spectroscopy enhanced by Deuterium oxide to discern antimicrobial mechanisms (Karlo et al., 2024).



• Dependence on relative humidity in the formation of reactive oxygen species in water droplets.: Investigates how relative humidity influences the generation of reactive oxygen species in water droplets, using analytical techniques that include Deuterium oxide (Mofidfar et al., 2024).



• Hydrophilic Interaction Liquid Chromatography-Hydrogen/Deuterium Exchange-Mass Spectrometry (HILIC-HDX-MS) for Untargeted Metabolomics.: This study presents a method integrating Deuterium oxide for untargeted metabolomic analyses, providing a comprehensive approach to biochemical analysis (Cajka et al., 2024).



• Blood compatibility of poly(propylene glycol diester) and its water structure observed by differential scanning calorimetry and (2)H-nuclear magnetic resonance spectroscopy.: Explores the interaction between polymers and water, where Deuterium oxide plays a crucial role in enhancing the sensitivity of nuclear magnetic resonance spectroscopy (Mochizuki et al., 2024).
