Page 11: ４ ． Measuring Mechanism
4. Measuring mechanism 4-1 Detecting system This detector has adopted a two-electrode system, and the detection cell and flow line are as shown in Fig. 4-1. In Fig. 4-1, a current proportional to the electrical conductivity of eluent is output from electrode I when an ac voltage is applied to electrode II. -
Page 12: ４－２ Electric System
4-2 Electric system The electric system of Shodex CD-200 consists of an oscillator (generating AC voltage), a signal processing circuit, a display/keyboard circuit, and two temperature control circuits. Fig 4-2 shows a block diagram of the electric system. The oscillator applies AC voltage to the cell, generating an electric AC current proportional to the electrical conductivity of the eluent, in the cell electrode. -
