  • Page 14: Overview And Specifications

    1. Overview and Specifications 1.1 Overview 1.1.1 Principles of CD operation When linearly-polarized light passes through an optically-active substance, its two circularly polarized components (i.e. the right and left circularly polarized beams of light) travel at different speeds, and are absorbed in differing degrees by the substance. Thus, the light that passes through the substance is elliptically polarized, and the substance is said to have “Circular Dichroism (CD)”.

    Thus, the ratio between I and S can be approximated with a sufficiently high accuracy for practical applications. If E and E represent the output voltages of photomultiplier tube corresponding to light intensities I and S, respectively, then S/I . By substituting this expression into equation (6), it can be expressed as follows: (1-7) If E...

    Therefore, once the AC signal has been calibrated using a standard sample, the correct CD and LD value can be determined. Figure 1.3 and Figure 1.4 show the block diagrams of the electrical system. J-1100 can get the signal from one detector and simultaneously measure CD/LD/Absorbance/HT voltage/DC voltage (up to four).
