Description
Multi-component calibration standards are available for the current version of this method with the 4 component deuterated internal standard mixture. The internal standard mixture is in the ratio Benzene-d6, 2 ml, Ethylbenzne-d10, 2 ml, Naphthalene- d8, 1 gram and Toluene -d8, 7 ml. The standards have the following nominal compositions.
