Cd spectrometer experiment
WebSample Preparation for CD Measurements When preparing a sample for CD measurements the absorption of light must be consid ered. For normal light the optical density (OD) of the sample is given by the Beer-Lambert law: OD = ε*l*c, where ε is the extinction coefficient (OD/cm*Molar), l the path length (cm) and c the sample concentration (Molar). WebUsing the black knob located on top of the flow control, slowly adjust the flow of nitrogen such that the CD reads 25 ft3/hr (Fig. 4). The measurement should be read at the top of …
