Deuterated hexane
WebDeuterated solvents are primarily used in preparing samples for solution-state nuclear magnetic resonance (NMR) to reduce the intensity of the solvent resonance. CIL offers a wide selection of deuterated solvents which would work with almost any sample type. CIL’ solvents are packaged in a variety of conveniently-sized ampoules and bottles. WebBurdick & Jackson solvents are arranged in order of increasing dielectric constant, the ratio of the electrical capacity of a capacitor filled with the solvent to the electrical capacity of the evacuated capacitor (at 20°C unless otherwise indicated).
